4When a character is not given a full name, only their first or last. Often happens because of TheLawOfConservationOfDetail, as in many cases, it's easier for the writers to not bother including a full name, and the audience doesn't need it. It can also be that a singular name is more familiar to the audience, as usually people don't refer to others they know by their full names. One could compare this to FirstNameBasis or LastNameBasis. UnnamedParent can also fall under this.

6In older (pre-1900 in North America; pre-1970 in the UK) fiction, a narrator may refer to a character (especially an older or more socially prominent character) by their [[LastNameBasis surname]]. This is because at that time, given names were much less commonly used socially than they are now; a young character may not even know the given name of an older character they are not related to. It was also common in that time to [[SpellMyNameWithABlank blank out]] the names of real people to avoid lawsuits and the like. This is often true in Japanese media set in the modern day as well, as given names are seen as being incredibly personal and sometimes not even used by close friends who still opt to address someone by their family name. Interestingly, the reverse is true if the work is set in some periods of Japanese history where the size of many of the clans that dominated society meant that it was hard to figure out whom one talking about if one just used the family name, so given names were used more instead. In other Asian media, however, one will often hear people referred to by their given names, but almost never by their family names -- partly because of the low diversity of family names in many Asian languages.

8A common joke is to do TheUnReveal on the full name.

22[[folder:Anime & Manga]]
23* Very few characters in ''Manga/Acca13TerritoryInspectionDept'' have both personal names and family names. Aside from Jean Otus, his sister, and their parents, everyone has only either a first name (Nino, [[spoiler:the other]] Dowa royalty), or a family name (the rest of the characters). This is especially obvious when all three Lilium brothers show up, and the only way to differentiate them is by their (very similar) job titles -- District Chief Lilium, Chief Officer Lilium, and Branch Chief Lilium -- or by birth order (Chief Officer Lilium, the most major character, is the middle brother).
24* Fitting its WorkCom setting, ''Anime/{{Aggretsuko}}'' gives only a single name for most of the cast, not even specifying if they're given or family names. Most strangely, the final season reveals Haida had been on a LastNameBasis, and gives full names for his father and brother, but not Haida himself.
25* ''Manga/AzumangaDaioh'' does this with Sakaki, Kagura, Kaori, Chihiro, and Mr. Kimura, all of whom are exclusively referred to by one name (with Kaori more often than not going by her nickname, Kaorin). With Sakaki and Kagura, it's never explained if those are their first or last names, though with the other characters, it's more obvious.
26* ''Manga/{{Berserk}}'': A huge amount of characters, including the main 3 of Guts, Griffith, and Casca have never had their last names revealed. While it makes sense for the former 2 considering Guts grew up with an abusive step-parent and had to flee after killing him in self-defense at a young age, and Griffith was implied to be a street urchin orphan, but Casca lived with her parents until she was 12, and the numerous other important characters who don't have their first names ever revealed don't have a justification either.
27* ''Manga/BGataHKei'': Yamada, the protagonist, was never given a first name in the series. This is {{lampshade|Hanging}}d by the author in the author's notes on the final page.
28* The surname of Dino, the Italian manager in ''Manga/BlendS'', is never given.
29* Many of the main characters of ''Anime/ElCazadorDeLaBruja'', Nadie, Ellis, Ricardo, L.A., and Lirio.
30* Though most of the devils and fiends in ''Manga/ChainsawMan'' genuinely have OnlyOneName, many of the human characters are only referred to by one name, including Denji, Himeno, Makima, and Kishibe. Denji is almost certainly going by his given name, but the others are more ambiguous. [[spoiler:And Makima is a humanoid devil, so that might ''actually'' be her only name.]]
31* ''Manga/DeliciousInDungeon'' has Senshi, Marcille, Chilchuck, Namari, Kabru... really there are more characters known by only one name than there are those with full names. However, eventually, official extra publications do start to give the cast their full names.
32* ''Manga/DemonSlayerKimetsuNoYaiba'', in general the series has the vast majority of its cast with established full names, and just a few extremely small backstory characters with no name given at all, but there is the odd ones out where they are family members, usually parents, of fully named characters with unknown given names, such as both deceased Shinobu Kocho’s parents, Muichiro Tokito’s parents and Yoriichi Tsugikuni’s father, the latter being particularly strange since his mother’s full name is revealed in extra materials but the rest remains left unknown to the audience.
33* Kyu from ''Manga/DetectiveSchoolQ'' never has a last name mentioned in the show. His DisappearedDad's full name is revealed at one point, but the fact that his identity comes as a surprise suggests strongly that Kyu and his mother have a different surname.
34* Poked at at the end of the manga ''Manga/EerieQueerie''. In the omake afterwards the two characters decide that they can finally call each other by their given names, only for Hasanuma's name to be *bleeped* out.
35* ''Anime/ElfenLied'': Almost every character only has their first name disclosed, with the two exceptions of Mariko Kurama and Anna Kakuzawa.
36* ''Anime/FinalFantasyVIIAdventChildren'': Denzel is the only heroic character without a surname, barring the Turks (see Video Games below).
37* In ''Anime/FutariWaPrettyCure'' and ''Futari Wa Pretty Cure Max Heart'', Yuriko's family name is never spoken by any character, despite her being a relatively major recurring character (and more minor characters typically got full names, the only-barely-recurring Chiaki Yabe being a particularly good example).
38* ''Manga/GAGeijutsukaArtDesignClass'':
39** The Tomokane siblings don't have their first names revealed, and both are simply known as "Tomokane" by their respective social circle. They even refer to each other as "bro" and "sis" rather than by name.
40** Art Club members Homura, Uozumi, and Mizubuchi have only one known name. It's unclear if their names are first or last names.
41** Among the teachers, Sasamoto-sensei isn't given a first name, although her students nickname her "Tono".
42* ''Anime/GhostInTheShellStandAloneComplex'': Most members of Section 9 go by one name only; the last episode of the first season reveals that these are just codename aliases with the exception of Togusa, who uses his real family name, presumably because it would get awkward if his wife learned that his coworkers call him by a different name, especially since as far as she knows, he is an employee of a security firm, not a Public Security agent. Togusa is thus an example of this trope, as his personal name has not been revealed.
43* In ''Manga/GourmetGirlGraffiti'', Shiina is known only by her family name, despite being one of the three central characters.
44* ''Manga/HanamaruKindergarten'': Most everyone in has only one name, though for a few characters we can infer their full name, or a full name is given. Most of these characters are either major characters or related to them.
45* When Hidekaz Himaruya revealed the human names of the ''Webcomic/HetaliaAxisPowers'' characters, he was asked why Germany didn't have a last name. To this, he replied, "You'll see someday." EpilepticTrees ensued.
46* No one in ''Manga/HidamariSketch'' has their full name revealed; characters are only referred to by either their given or family names.
47* ''VideoGame/InazumaEleven'':
48** Played with in the case of original series Hiroto. He keeps his original last name, Kiyama, after being adopted, but his first name is changed to Hiroto after the deceased son of Kira Seijirou. His original first name was not revealed until ''Ares''.
49** Only one of Shuu's names is revealed (it's unknown whether it's his given or family name), but considering he had a sister (who is only known as "Shuu's sister"), it's likely he has a full name.
50** There are three Furukabu brothers, but none of them have a mentioned given name.
51* Sonya from ''Manga/KillMeBaby'' is only known by her first name. Her lack of a family name keeps her as NonSpecificallyForeign.
52* Caren, Coco, Noel, Sara and, actually, ''most'' characters of ''Manga/MermaidMelodyPichiPichiPitch'' have only one name revealed to the audience; the exceptions are the main trio and the men in their lives (although, in the manga, Hamasaki has only one name too).
53* In ''Manga/MinamiKe'', almost every character has only one name revealed, regardless if it's the first name or family name. The only characters with full names are the Minami characters and Yuka Uchida.
54* ''Manga/MissKobayashisDragonMaid'': The titular Kobayashi is only addressed by her family name. Neither her maid/ImpliedLoveInterest, adoptive child, best friend, or even her parents refer to her as anything else.
55* In ''Manga/MoriartyThePatriot'': Miss Moneypenny, Miss Hudson, and Von Herder are only ever referred to by their last names. Presumably they ''have'' first names, as everyone else does, but what they ''are'' is not revealed. Since Von Herder is often referred to as simply "Herder" it's questionable if the author might think "Von" was intended to be his first name (which it is not).
56* In ''Ogawa San and I'', the main character's coworker Ogawa is only referred to by her family name, since while the main character has an UnrequitedLove for Ogawa, the two are not especially close. After Ogawa gets married, her husband's last name is never revealed.
57* In ''Manga/OnePiece'' only about half of the Straw Hats have a known last name. Nami, Usopp, Brook, Jimbei and possibly Franky (his real name is Cutty Flam, it being unknown if Flam is his last name, or part of his first name) however only have their first names revealed in the story.
58* ''Franchise/{{Pokemon}}'':
59** Most if not all characters in [[Anime/PokemonTheSeries the anime]] only have one name. In the English version, the only main characters with known last names are Ash Ketchum, the regional professors (and by extension Gary Oak, Ash's first rival), and Tracey Sketchit. ''None'' of them had last names in the Japanese versions (the "Ketchum" was made to match the lip flaps of "Satoshi", while Shigeru/Gary is never referred to by his grandfather's name). Once in a great while, a random Character of the Day will have a last name (the best examples being the Hoenn champion Steven Stone ["Daigo Tsuwabaki"] and Giselle [Seiyo Yuto] in the Japanese version), but then we often won't know their first name.
60** As with most ''Pokémon'' media, ''Manga/PokemonAdventures'' counts. In ''Adventures'' out of all the Pokédex Holders only [[DubNameChange Blue]]/Green Oak, Sapphire Birch, Platinum Berlitz, and [[DubNameChange Yvonne]]/Y Gabena have last names, and that's only because the first two are related to Professors and Platinum was due to no third game being known when she was first shown (so she was called by a surname until ''[[VideoGame/PokemonDiamondAndPearl Pokémon Platinum]]'' was released). Y is an exception because her game counterpart ([[VideoGame/PokemonXAndY Serena]]) has no known surname and her last name isn't game-related.
61** This trope is made noticeable in ''Manga/PokemonDiamondAndPearlAdventure'' when Mitsumi says she is no longer on a FirstNameBasis with [[spoiler:Cyrus]]. The problem is we never even hear his, or anyone else's, last name.
62* In ''Manga/RanmaOneHalf'', Principal Kuno's first name is never given.
63* In ''Manga/SaiKano'', none of the characters, including protagonists Shuji and Chise, get full names. Apparently mangaka Shin Takahashi thought they weren't necessary for readers to empathize with them.
64* In the ''Anime/SonicTheHedgehogTheMovie'' OVA, Sara's last name is never given. Her dad is only referred to as [[EveryoneCallsHimBarkeep Mr. President]].
65* ''Anime/YesPrettyCure5'':
66** Karen's butler is known exclusively as Jiiya (a term for an older butler) or Sakamoto-san, with his given name unrevealed.
67** Nozomi's father's family can be inferred, but he has no given name to call his own.
68* ''Manga/{{Yotsuba}}'':
69** For the longest time, Dad is simply known as "Koiwai", with even his best friend Jumbo referring to him with his family name. It wasn't until his mother comes to visit in chapter 86 do we get to learn his given name, Yosuke.
70** One of Dad's friends is nicknamed Yanda. His actual last name is Yasuda, but his first name is not given.
71** Torako and Hiwatari, Asagi and Fuuka's respective best friends, don't have their last names revealed.
72* ''Anime/YuGiOh5Ds'' never gives last names to Lua, Luca, Bruno, Yeager, Bommer, Demack, any of the Emperors of Yliaster or members of Team Unicorn, Team Catastrophe, and Team Ragnarok. Which is actually very strange, because most characters are given them.
73* ''Anime/YuGiOhArcV'': Of the many characters who do not have last names (with most of said characters being orphans), Yuto is probably the oddest case. There's never any mention to his family, but he was living a perfectly normal life going to school and all, and all his friends have family names, so it's weird that we never hear his -- especially since other characters introduce themselves with their full names. It turns out to overlap with {{Foreshadowing}} because [[spoiler:it's a hint that he's one of Zarc's reincarnations and never had biological relatives]], but not having a last name in a modern city trying to live a normal life is... pretty weird.
74* ''Anime/YuYuHakusho'': The Toguro brothers' given names are never revealed. They're only ever distinguished as Younger Toguro and Elder Toguro.
75[[/folder]]
76
77[[folder:Comic Books]]
78* ''ComicBook/DoctorStrange'': Doctor Strange's faithful servant is known only as Wong. Lampshaded in a comic ''Defenders'' series when Nightmare asked if 'Wong' were his first or last name -- and followed up Strange's exasperated silence with "You don't know, do you?" (in the Franchise/MarvelCinematicUniverse at least it's implied he has OnlyOneName)
79* ''ComicBook/HuntersHellcats'': It is never established what Heller's first name is, and no one ever refers to her as anything other than Heller.
80* ''ComicBook/TheMask'': Lt. Kellaway never earns a first name, which is lampshaded a few times ("Lieutenant, what exactly ''is'' your first name?"). WordOfGod says it's ''Prometheus''. In [[Film/TheMask the movie]] and subsequent cartoon it's "Mitch".
81* ''ComicBook/TheWalkingDead'': Half the (large) cast, which necessitated them to be {{named|ByTheAdaptation}} in [[Series/TheWalkingDead2010 the TV adaptation]]. Such main characters include: Glenn, Andrea, Carol, Tyreese, Sophia, Heath, and Negan.
82* ''ComicBook/XMen'':
83** Bishop was known only by his surname for years before his first name was revealed to be Lucas during the ''X-Treme X-Men'' series.
84** Sage is another X-Man to not have a full name. ''Tessa'' is believed to be a part of her name, but it is unknown as to whether this is her first name, last name or even just an alias.
85[[/folder]]
86
87[[folder:Comic Strips]]
88* When ''ComicStrip/{{Arnold}}'' began, characters Arnold and Tommy didn't have last names. This all changed, however, when the creator did a contest asking fans to send ideas for their last names. The winning names were Arnold ''Melville'' and Tommy ''Jordon''.
89* Any character in ''ComicStrip/CalvinAndHobbes'' who isn't Susie Derkins has no known full name. The only other characters with full names are the [[TheGhost unseen]] Tommy Chestnutt and Russy White.
90* Miss Lace, in the WWII comic feature ''ComicStrip/MaleCall'' was known only by that name, and refused point-blank to answer a direct question as to whether 'Lace' was her first or last name.
91* ''ComicStrip/{{Mafalda}}'': Mafalda's surname is never stated. One strip showed a school test of hers with the panel boundary cutting off all but part of the first letter of her surname.
92* ''ComicStrip/{{Peanuts}}'':
93** The full names of Marcie and Schroeder are never revealed.
94** Other characters ''were'' given last names, but these were hardly ever used, meaning that these characters effectively remained without surnames for most readers. For example, Peppermint Patty's surname (spoken only once) was "Reichart" (pronounced "rike-hart").
95* ''ComicStrip/{{Popeye}}'': Apparently, Popeye wasn't even aware of his full name. One story during the Sagendorf years revolved around Popeye trying to get Poopdeck Pappy to tell him what their last name is. It was apparently so horrible, when he finally did learn what it was, he hid in shame until Wimpy finally talked him out of hiding.
96[[/folder]]
97
98[[folder:Fan Works]]
99* ''Fanfic/AbraxasHrodvitnon'': Dr. Mariko, Nadezhda, Esfir, and Lubyov are only known by their first names. Tejada and Sergeant Travis meanwhile are only known by their last names.
100* ''Fanfic/DungeonKeeperAmi'': Ami's mother, Dr. Mizuno, has only her surname known, because no character who'd call her by her first name has been seen.
101* ''Fanfic/{{Evershade}}'': Kyle Yates's best friends, Owen and Lauren, don't have their surnames mentioned.
102* ''Fanfic/EverydayCrazinessInPontypandy'': Mr. and Mrs. Adelstrop never have their first names revealed. Their baby, however, is named Elsa.
103* The most important human characters in ''Fanfic/FriendshipIsOptimal'' are only known by their first names.
104* ''Fanfic/MikesNewGhostlyFamily'': Mike Schmidt is known only by his first name and the last name he took from his adoptive father. His birth surname is never revealed, and, according to the author, "[[invoked]][[ShrugOfGod Mike's [birth] last name is whatever you want it to be. As far as he is concerned, Schmidt is his last name]]".
105* Karui mentions during the final arc of ''Fanfic/SonOfTheSannin'' that the people of Kumogakure have a social norm of never using their last names outside of official documentation to show that their first loyalty is to the village and cut down on clan rivalries. Her boyfriend Choji wasn't even aware that she ''had'' a last name until this point despite having known her for several years.
106[[/folder]]
107
108[[folder:Films -- Animation]]
109* ''WesternAnimation/AnAmericanTail'' has Bridget with only a first name, in a series that usually prides itself in coming up with creative [[SpeciesSurname Species Surnames]].
110* The tombstones of Elsa's and Anna's parents from ''WesternAnimation/{{Frozen|2013}}'' only list their names as "Agdar" and "Idunn" when translated. None of the characters are given last names except for Kristoff. In [[WhatCouldHaveBeen development]], Hans was known as "Admiral Westerguard"; WordOfGod says that can still be considered his surname and it's been used in media like ''Literature/AFrozenHeart''.
111* In ''WesternAnimation/TheNightmareBeforeChristmas'', Sally has no last name, though fans usually give the last name of [[MadScientistsBeautifulDaughter Finklestein]], [[ExactlyWhatItSaysOnTheTin Ragdoll]], or in FanFics where she's married to Jack, Skellington.
112** The [[Literature/TheNightmareBeforeChristmasLongLiveThePumpkinQueen sequel novel]] now officially gives it as Skellington.
113* The Mayor of the City of Frank in ''Film/OsmosisJones'' is only ever referred to as 'Mayor Phleghmming'; a first name is never given.
114* ''WesternAnimation/RiseOfTheGuardians'': Jack's last name before it became "Frost" is unrevealed. Likewise, Jamie and Sophie are the only two kids out of the kid group to have their last name (Bennett) revealed.
115[[/folder]]
116
117[[folder:Films -- Live-Action]]
118* ''Film/AreYouBeingServed'': We don't get to know Conchita's surname.
119* ''Film/{{Beetlejuice}}'': Juno presumably has a surname, but it's never revealed.
120* ''Film/{{Clara}}'': Clara's last name is never revealed. She's only called by her first name.
121* ''Film/CynaraPoetryInMotion'': Cynara and Byron's other names, assuming they have any, aren't revealed.
122* ''Film/DadsArmy1971'': We don't get to know General Fullard's first name.
123* ''Film/DoctorSeries'':
124** ''Film/DoctorInTheHouse1954'': We don't get to know Stella's surname.
125** ''Film/DoctorAtSea'': We don't get to know Easter, Trail, or Fellowes' first names.
126** ''Film/DoctorAtLarge'': We don't get to know Dr. Hatchet's first name.
127** ''Film/DoctorInLove'': We don't get to know Leonora or Dawn's surnames, or Dr. Mincing, Lady Spratt, and Wildewinde's first names.
128** ''Film/DoctorInDistress1963'': We don't get to know Dr. Blacker's first name.
129** ''Film/DoctorInClover'': We don't get to know Miss Sweet, Nurse Bancroft, Professor Halfbeck, and Nurse Holiday's first names.
130** ''Film/DoctorInTrouble'': We don't get to know Humphrey or Roddy's surnames, or Mrs. Dailey and Satterjee's first names.
131* ''Film/{{Duel}}'': In the original story by Creator/RichardMatheson, Mann has no first name, while his wife has one. In the film, this is inverted; David Mann has a full name given, but his wife doesn't.
132* ''Film/TheEarringsOfMadameDe'': Andre and Louise's last name is never mentioned. Once someone forgets it, once Louise is cut off by some noise when saying it, and two times their name on a card is obscured by a bit of scenery.
133* ''Film/EdwardScissorhands'': Jim, Kim's [[RomanticFalseLead boyfriend,]] is only called by his first name and his last name is never revealed. It's notable that his last name is never given because not only is he the BigBad, but a burglary at his family's home serves as a plot point.
134* ''Film/FireTwister'': Only the main characters in the cast are named at all, and most of them are only given a first name (Scott, Carla, etc.). The only one to have a surname is [[BigBad Mitch Garber]][[note]]Even then, his surname is only said within the movie. The ending credits don't cite it at all.[[/note]]. Meanwhile, V is known only by her codename.
135* In the ''Franchise/JamesBond'' films, Miss Moneypenny's given name was never revealed prior to the Craig reboot. Played with when the reboot version of the character was introduced; her given name is one of the first things the audience learns about her, but it's only later that [[CanonCharacterAllAlong her surname is revealed]].
136* Throughout the entirety of ''Film/LegallyBlonde'', Professors Callahan and Stromwell are exclusively referred to by their surnames, with their first names never being established.
137* ''Film/TheKarateKid'' film series has a few:
138** ''Film/TheKarateKid1984'' has Cobra Kai members Dutch, Tommy, and Jimmy.
139** ''Film/TheKarateKidPartII'' has female lead Kumiko, her aunt Yukie, and Yuna[[note]]Retroactively, as Yuna [[NamedInTheSequel wasn't named until]] the SequelSeries ''Series/CobraKai''[[/note]].
140** ''Film/TheKarateKidPartIII'' has Cobra Kai associates Dennis and Snake.
141* ''Film/LiberalArts'': Protagonist Jesse Fisher and Professors Peter Hoberg and Judith Fairfield are the only characters in the film with given full names.
142* ''Film/{{Margarita}}'': None of the characters get their last names revealed, only the first ones.
143* ''Film/MaryPoppins'': The head of Fidelity Fiduciary Bank, Mr. Dawes Sr., never has his first name spoken. His son, Mr. Dawes Jr., presumably has the same name, but it's never spoken either, even in ''Film/MaryPoppinsReturns''.
144* ''Film/AMatterOfFaith'': Both Kamen and Portland are only addressed by their last names.
145* ''Film/NoKidding'': We don't get to know Vanilla's surname or Tandy and Mrs. Spicer's first names.
146* ''Series/OnTheBuses'' films:
147** ''Film/OnTheBuses'': We don't get to know Betty or Bridget's surnames.
148** ''Film/MutinyOnTheBuses'': We don't get to find out Susy or Nymphy Norah's surnames or Mr. Jenkins' first name.
149** ''Film/HolidayOnTheBuses'': We don't get to know Joan's surname.
150* More than half of the named characters in ''Film/{{Payback}}'' only ever get one name used. The VillainProtagonist is Porter, the HighClassCallGirl [[HookerWithAHeartOfGold with a heart of gold]] is Rosie, the [[BondageIsBad dominatrix]] connected to a [[TheTriadsAndTheTongs Triad gang]] is Pearl. The [[CorruptCop crooked cops]] are Hicks and Leary. TheDon of TheSyndicate is Bronson, whose [[CoDragons two subordinates]] are Carter and Fairfax. Lampshaded when Carter asks Porter's TokenMotivationalNemesis Val Resnick for Porter's first name, and Val tries to think for a minute before admitting he has no idea and has only ever heard him called Porter.
151* ''Film/PleaseTurnOver'': We don't get to know Beryl's surname.
152* ''Film/ThePostman'': Most of the characters (including the titular Postman) are not referred to with anything except just one name (first, last or nicknames).
153* In TheFilmOfTheBook ''Literature/{{Rebecca}}'': the main character is never called anything but "Mrs. [=DeWinter=]" on screen.
154* ''Film/RaisingTheWind'': We don't get to find out Sid or Harry's surnames.
155* In ''Film/Revenge2017'', none of the characters ever have their family names revealed.
156* ''Film/TheRoom2003'': Everybody except for Claudette's unseen friend Shirley Hamilton. The closest thing anyone actually has to a last name is "Chris-R".
157* Most of the characters in earlier ''Franchise/{{Saw}}'' films have full names, but characters with only a first name or surname become prominent in later movies. While many of them have minor or supporting roles, there are still major ones without a full name, such as most of the barn game victims from ''Film/{{Jigsaw}}''.
158* ''Film/Scarface1983'': Several examples.
159** Hector the Toad.
160** Alberto the Shadow.
161** Subverted with Tony's mom. Her first name is given as Georgina in the ClosingCredits.
162* ''Film/{{Sheroes}}'': None of the characters in the film's last names are revealed.
163* The majority of the sidekick cadre in ''Film/SkyHigh2005'' don't have last names given.
164* ''Film/SleepingDogs1977'': The main character is referred to with his last name Smith, or "Smithy" for a nickname, while major characters Bullen and Jesperson are never referred to by first names either. [[spoiler:Though in a FreezeFrameBonus when Smith's police file appears, it shows that his first name is Martin]].
165* ''Film/SmokeyAndTheBandit'': Frog's first name is "Carrie", but her last name is never revealed.
166* The Franchise/MarvelCinematicUniverse has an interesting example with Ned, Peter Parker's best friend. While his last name isn't spoken out loud in the ''Film/SpiderManHomecoming'', his comic book counterpart has the surname Leeds. His last name wouldn't be officially spoken until ''Film/SpiderManNoWayHome''.
167* ''Franchise/StarWars'':
168** Palpatine was an example until 2014 -- nearly four decades after the character was conceived -- when the reboot novel ''Literature/StarWarsTarkin'' officially established his birth name as "Sheev Palpatine". Similarly, Ackbar was belatedly given a first name to become "Gial Ackbar". The prequel story ''Literature/DarthPlagueis'' (written before the reboot) tried to justify Palpatine's lack of a first name by revealing that he hates his immediate family enough to want to distance himself from the name that they gave him, but still takes pride in his older aristocratic lineage. It's implied that his full name is Cosinga Palpatine II, referencing Creator/GeorgeLucas's very first draft of ''Franchise/StarWars'', in which the Galactic Emperor's name was "Cos Dashit", which in turn inspired the erroneous but very common fanon name "Cos Palpatine".
169** Count Dooku. Other [[Franchise/StarWarsExpandedUniverse EU sources]] make it clear that "Dooku" is a family name. There are other members of his family who are given first names, but the Dooku that we see on-screen hasn't been given one as of yet.
170* ''Film/TwiceRoundTheDaffodils'': We don't get to know Nurse Catty, Joyce, Dora, or Janet's last names. The latter is humourously {{Lampshaded}} as the others all refer to her as "Janet What's 'Er Name?".
171* ''Film/UpTheFront'': We don't get to find out Lurk, Groping, or Colonel von Gutz's first names or Fanny's last name.
172* ''Film/VioletAndDaisy'': Violet and Daisy are never referred to with anything except these names. Neither's last name is revealed in the film.
173* ''Film/WatchYourStern'': We don't get to find out Blissworth, Commander Phillips, or Chief Mundy's first names.
174[[/folder]]
175
176[[folder:Literature]]
177* ''Literature/AlexanderAndTheTerribleHorribleNoGoodVeryBadDay'': Alexander, Anthony, and Nick's last name is unrevealed, while Mrs. Demson and Mrs. Dickens's first names are unrevealed.
178* The majority of human characters in ''Literature/{{Animorphs}}'' are only known by their first names. The protagonists narrate at the start of each book that they can't tell you their last names because it'll make it easier for the Yeerks to find them. [[spoiler:Jake's surname is revealed to be Berenson in the second-to-last book.]]
179* ''Literature/Area51'': Many of the military antagonists in the first book don't have their first names shown. This is fairly standard for military address of course.
180* ''Literature/ArtemisFowl'' series:
181** Students of Madame Ko's Personal Protection Academy are instructed never to reveal their first name to the principal (person they are body-guarding), in order to keep the relationship between them strictly professional. Because of this, [[BattleButler Butler's]] first name is not known by Artemis, or the reader, [[spoiler:until he tells Artemis that his first name is "Domovoi" in the third book because he thinks he's on the brink of death and it no longer matters]].
182** Foaly's first name is never given.
183* In ''Literature/BasilOfBakerStreet'' (and ''WesternAnimation/TheGreatMouseDetective''), most mouse characters have full names (like Dr David Q. Dawson) but Basil is only known by that name (although "of Baker Street" is sometimes used for a "full name" effect). It can be presumed it's his surname (by analogy to how nobody except Mycroft calls Holmes "Sherlock", not even Dr Watson, and because he once mentions a sister named Brynna Basil), but his first name is never revealed. Likewise, the Irene Adler counterpart, Mademoiselle Relda, only has one name.
184* In the children's book ''The Booger That Escaped'', Luke and Clara's surnames are unstated.
185* ''Literature/CatchTwentyTwo'': Major _____ de Coverly, who is so forbidding in appearance that nobody dares to ask his full name.
186* ''Literature/{{Charly}}'': The [[LoveTriangle romantic rival,]] Mark, is only referred to by his first name and his last name is never revealed.
187* ''Literature/DarcyAndGranDontLikeBabies'': Darcy's last name is unrevealed.
188* ''Literature/DiaryOfAWimpyKid'': Unlike Greg's other friends, Fregley's last name is not revealed.
189* ''Literature/DirtyBertie'': Bertie's last name is Burns, Eugene's is Clark, Nick's is Payne, and Angela's is Nicely. However, we don't know what Darren's last name is.
190* ''Literature/{{Divergent}}'': Only select characters have known full names. Tris' best friend, Christina, notably never has her surname revealed, even after her birth family are introduced in the third book.
191* ''Literature/DoctorOmega'': Doctor Omega's assistant Fred.
192* This is a major plot point of ''Don't Go with Strangers'', where Lu counts Ralph and Mrs. Smith as strangers since she doesn't know their entire names. Incidentally, we never find out the last name of Lu and her brother Phil either.
193* ''Literature/{{Dracula}}'': Count Dracula's first name is never given.
194* ''Literature/TheDresdenFiles:''
195** Sanya's last name is never revealed, and it's not clear whether he has one or not.
196** Lord Raith, King of the White Court of Vampires and BigBad of ''Literature/BloodRites'', is only ever referred to by his title or surname. His children (or at least the plot-important ones) do have given names, but his is never revealed.
197* ''Literature/DrSeusssSleepBook'':
198** The first names of the Herk-Heimer Sisters are unknown.
199** We see that three members of the Hinkle-Horn Honking Club are named George, Henry, and Freddy, but we don't know their surnames, if they have any.
200** We don't know the first names of Mr. and Mrs. J Carmichael Krox, nor what the "J" stands for.
201* ''Literature/GarrettPI'':
202** Garrett's first name has never been revealed. Presumably he does have a first name, as we know his brother had one (Mikey). We know his mother's pet name for him ("Wart") and the nickname he went by in the Marines ("Wrecker"), and it's been implied that he was named after some long-dead relative, but Cook's still being coy about his given name.
203** Winger's full name has never been revealed. It's less clear in her case whether there's anything more to reveal; given her history, her name might be an alias and "Winger" might be the whole thing.
204* In Creator/CharlesDickens' ''Literature/GreatExpectations'', the main character Pip is raised by his sister and her husband Joe. Joe's surname is not revealed, and his wife is referred to only as "Mrs. Joe" for most of the book until it's mentioned near the end that she's named Georgiana after her mother.
205* ''Literature/HarryPotter'' is usually meticulous when it comes to characters' identification, making it notable when a character's full name is ''not'' disclosed.
206** Molly Weasley's aunt Muriel is only known by that name. It is unknown whether she is Molly's aunt by blood or marriage, whether she is aunt from her father's or mother's side, and whether she is married, so we can't deduce her surname for sure.
207** Fleur's father is only known as Monsieur Delacour. His wife, on the other hand, is named (Apolline Delacour).
208** The books never mention Ollivander, Myrtle, and Gregorovitch's full names. WordOfGod, though, eventually revealed that they are Garrick Ollivander, Myrtle Warren, and Mykew Gregorovitch.
209* ''Literature/HaruhiSuzumiya'': Side characters are either known by just one name, or [[NoNameGiven no name at all]]. If a character's full name is given, that character is supernatural in some way.
210* ''Literature/TheHungerGames'':
211** Among the Hunger Games tributes, only Katniss, Peeta, Haymitch, Johanna, Finnick, and Annie have their full names revealed. Katniss never finds out about Rue's last name despite befriending her, and Beetee similarly has his last name unrevealed even after he moves to District 13, where everyone are customarily called by their last names.
212** Aside from Katniss, Gale, and Finnick, the Star Squad members go by their last names only. The Leeg twins are nicknamed "Leeg 1" and "Leeg 2", rather than first names, because they opt to stick to formality. The propo team (Cressida, Messalla, etc.), on the other hand, go by their first names only.
213* ''Literature/ImInMarsportWithoutHilda'': Max, the CharacterNarrator, is only referred to by his first name. By extension, so is Hilda, Max's wife. Flora, his girlfriend, is referred to only by her first name as well. It would seem as if all the characters were going to be given only one name, but then Rog Crinton, Max's boss, shows up and tells him to investigate Edward Harponaster, Joaquin Lipsky, and Andiamo Ferrucci.
214* ''Literature/{{Indexing}}: Reflections'': The Jack that built The House That Jack Built doesn't have his last name provided.
215* ''Literature/LittlePrincess'': Even when the Princess, Admiral, and Maid's names were revealed in the sequel series ''Not-So-Little Princess'', their surnames remained unrevealed.
216* ''Literature/LyttleLyttonContest'': [[http://adamcadre.ac/01lyttle.html 2001]]: The people in these entries:
217** Corn eater:
218---> Jeremy didn't remember eating corn or, for that matter, wearing his good loafers.
219--->--Michael Wells
220** Goat Inhabiter:
221---> Leon fell out of the goat.
222--->--Rob Tobias
223** Person:
224---> In anticipation, John licked his own lips.
225--->--Andrew Lloyd
226** Therapist:
227---> Hank, Herculean therapist, cleansed the Augean stables of my soul.
228--->--Peter Berman
229* ''Literature/LookingBackward'': Dr. Leete's first name is never revealed.
230* ''Literature/LordOfTheFlies'': Most of the characters are known only by their first name or a nickname. The exceptions are Jack Merridew, who attempts unsuccessfully to insist on LastNameBasis, and Percival Wemys Madison, who recites his full name and address as a MadnessMantra.
231* The title character of ''Literature/{{Lovejoy}}'' is never given a first name. In the [[Series/{{Lovejoy}} TV series]] adapted from the books, it is hinted that his name may be "Malcolm", but he does not confirm or deny this.
232* ''Literature/{{Matilda}}'': Hortensia and Lavender's last names aren't revealed despite all the other kids having theirs revealed.
233* In ''Literature/TheMidnightGang'': Nobody has their full name known except for Tom Charper and Quentin Strillers.
234* ''Literature/MobyDick'': We don't learn the full names of ''any'' main characters, not even Ishmael, the first-person narrator.[[note]]If that even is his name -- many readers have commented on the fact that the novel's first line is [[UnreliableNarrator "Call me Ishmael," instead of "My name is Ishmael."]][[/note]] Ahab is only ever known by his given name; even when he's referred to by rank, he's still "Captain Ahab."
235* In ''Literature/{{Mog}}'', Mr. and Mrs. Thomas's first names are unrevealed.
236* In ''Literature/TheMoonMaid'' and sequels by Creator/EdgarRiceBurroughs, the FramingDevice is a man named Julian recounting a series of adventures from his PastLifeMemories; he makes a point of not telling Burroughs' AuthorAvatar his full name because he doesn't want it getting around that he remembers other lives -- particularly since some of the lives he remembers ''haven't happened yet''.
237* The protagonist of Creator/AgathaChristie's ''Literature/TheMysteriousMrQuin'' is the elderly, and rather old-fashioned in manners, Mr Sattherthwaite. If he's on first-name basis with anybody it never comes up, and his given name is never revealed.
238* ''Literature/OneFishTwoFishRedFishBlueFish'':
239** Mr. Gump's first name is unknown.
240** We don't know the last name of Ned, the guy with the too-small bed, nor Joe (who was talking on the phone with another guy before a mouse cut the wire).
241* ''Literature/OthersidePicnic'' has Kozakura, who is known only as Kozakura.
242* None of the characters in ''Literature/OurWivesUnderTheSea'' have known surnames.
243* The protagonist of the Polish YA series ''Pan Samochodzik'' is only ever referred to as Tomasz. His last two initials are N.N., which could be a reference to his author's last name and pen name (Nowicki-Nienacki), or the abbreviation for the Latin ''nomen nescio'' ('name unknown').
244* ''Literature/{{Parker}}'', the VillainProtagonist of a series of novels by Richard Stark. Stark decided not to give the character a first name when he thought ''The Hunter'' was going to be a standalone novel. He stuck with this decision when it became a series, even though it complicated writing the subsequent books.
245* In "Paycheck" by Creator/PhilipKDick, we're never told the protagonist's first name -- he's consistently referred to only as "Jennings".
246* ''Literature/PeekABooPoo'': It's never stated what Alfie's surname is, nor that of Kate's boyfriend Colin in the sequel.
247* ''Literature/{{Phantastes}}'': Anodos, the protagonist.
248* ''Literature/ProphecyApprovedCompanion'': Multiple characters:
249** Mr. Clockwork, the Mr. implies he has a first name, but we don't know it.
250** The three Prophecy Approved Companions:
251*** Qube, the Mage Companion
252*** Quinton, the Warrior Companion
253*** Quince, the Hunter Companion
254* In ''Literature/{{Ratburger}}'', Tina Trotts is the only character whose full name is revealed. The other characters are only known by their first names.
255* ''Literature/TheRaven'': We don't know Lenore's last name.
256* ''Literature/{{Ravensong}}'': Almost every character, such as Stacey, the protagonist, her sister Celia, and their brother, Young Jim.
257* Several characters in the ''Literature/{{Redwall}} series have no stated full name. Most notably the eponymous Martin The Warrior, and his father Luke.
258** Several of the "vermin" characters are only referred to by one name, though this is likely a case of OnlyOneName
259* ''Literature/RepairmanJack'': F. Paul Wilson deftly avoids revealing Jack's last name, even in novels where other members of his family appear.
260* In the novelette ''Literature/ARoseForEcclesiastes'', the protagonist Gallinger's first name is never mentioned.
261* ''Literature/RoysBedoys'':
262** The Bedoys siblings and Maker Chan are the only kid characters with known last names.
263** Mr. and Mrs. Bedoys's first names are unknown, and when the books' web animation adaptations still had comments, the creator was asked via comment what Mrs. Bedoys's first name was and [[ShrugOfGod said she didn't know]]. We don't know the first names of Mr. Master, Mr. Sprinkles, or Mr. Chan either.
264* ''Literature/SickSimon'': Simon's last name and Ms. Slowinski's first name are unrevealed.
265* None of the sisters in ''Literature/SisterPrincess'' have family names and until the anime adaptation Wataru was only ever referred to by a form of 'brother'. This makes knowing whether they're half sisters or full sisters to each other impossible to tell.
266* [[BlindSeer Rezo the Red Priest]] of ''Literature/{{Slayers}}'', only known by his title. His great-grandson Zelgadis was this initially; however, his surname (Graywords) got mentioned in an interview with the creator, and it eventually gets mentioned several times.
267* Many, if not most, of the characters in ''Literature/SomeoneElsesWar'' are known by first name or nickname. Not counting the main character and his family, a grand total of ''three'' characters ever get a full name.
268* ''Literature/{{Spenser}}'' series by Robert B. Parker: Anytime someone asks, the detective protagonist simply replies with "Spenser." One time, when questioned if that was his first or last name, Parker writes the line "I told her."
269* ''Franchise/StarWarsLegends'':
270** ''Literature/TheIllustratedStarWarsUniverse'': In the official bio, Senior Anthropologist Hoole is known only by his title and last name, with his first name listed on as "indeterminate".
271** This continues in ''Literature/GalaxyOfFear,'' where even Hoole's own niece and nephew only know him as "Uncle Hoole." His full name is finally revealed in ''Army of Terror'' as [[spoiler: ''Mammon'' Hoole, unmasking him as one of the two geniuses behind Project Starscream.]]
272 * In ''Literature/TheStoryOfValentineAndHisBrother'', the twins' mother is simply Myra, or Forest Myra. Even her first name isn't mentioned until Chapter 18, and is only used a handful of times after that.
273* In ''Literature/SuperCub'', Koguma is only known by her family name while Reiko is only known by her given name.
274* None of the characters in ''Literature/{{Surfacing}}'' by Creator/MargaretAtwood have full names. The narrator's three companions are only known by their first names. (And the narrator herself is never named at all.)
275* ''Literature/TheTaleOfBenjaminBunny'': We don't know the [=McGregors'=] first names.
276* ''Literature/TheTaleOfMrsTiggyWinkle'': We don't know Mrs. Tiggy-Winkle's first name.
277* ''Literature/TalesOfThePack'': In ''Hungry Ghost'' Professor Rindt's first name is never said.
278* Laurent in ''Literature/ThereseRaquin''. We're never even told if that's his first or last name.
279* In the children's book ''Tim's Problem'', Tim's last name is never mentioned.
280* A minor character in ''Literature/ToKillAMockingbird'' is Mr. X Billups. [[SubvertedTrope Subverted in that]] Jem explains to Dill that X really is his name, not an initial.
281* In ''Film/TheTrial'' by Creator/FranzKafka, the protagonist is referred to only as Josef K.
282* Almost everyone in ''Literature/{{Uglies}}'', save for Tally Youngblood and Andrew Simpson Smith. Most of the ''Extras'' characters get last names, but we still never learn the last names of the characters from the original trilogy who show up. Dr. Cable is also only ever Dr. Cable, and David may not actually ''have'' a last name.
283* ''Literature/WarAndPeace'': Hundreds of characters. Zherkov, Raevsky, Tikhon, [[EvilChancellor Speransky]], [[TheStrategist Pfuel]], etc. Most of the historical characters are only referred to with one name (such as General Mack and Marshals Murat and Davout) since Tolstoy probably assumed anyone reading this book in 1870 would recognize the names from history lessons.
284* ''Literature/WinnieThePooh'': Christopher Robin's last name isn't revealed, though the real-life boy he was based on had the surname of "Milne" and in the movie ''Film/ChristopherRobin'', "Robin" is his last name.
285* In ''Literature/TheWitchFamily'', no one has a given last name.
286* ''Literature/{{Wyatt}}'': The protagonist is only ever referred to as 'Wyatt'. It is not until ''The Fallout'' (book 6 in the series) that the reader learns that Wyatt is his surname, when his nephew laments that he wanted to known as 'Wyatt', but couldn't because everyone in the underworld knew there was only one 'Wyatt': his uncle.
287[[/folder]]
288
289[[folder:Music]]
290* ''Music/{{Songdrops}}'': Christie, who featured in the Valentine's Day song, has an unrevealed surname.
291* The members of Music/{{Xera}} are only known by their first names.
292[[/folder]]
293
294[[folder:Podcasts]]
295* ''Podcast/CoolKidsTable'': In the ''Series/{{Firefly}}'' game, Caleb has no last name given.
296* In the OpeningNarration of ''Podcast/SporadicPhantoms'', Robin says that they can't tell you their last names out of fear of retaliation.
297* ''Podcast/WelcomeToNightVale'': Carlos the Scientist's last name is never revealed (unless it's literally "the Scientist"). Intern Dana, Old Woman Josie, Telly the Barber, and Kevin are also still going without surnames. Cecil was an example for the first 33 episodes, before his full name was revealed (it's [[spoiler:Cecil Gershwin Palmer]]. [[UnreliableNarrator Probably]]).
298[[/folder]]
299
300[[folder:Radio]]
301* On ''Radio/TheVinylCafe'', Stuart [=McLean=] went out of his way to not give Dave and Morley's family a last name, hilariously twisting himself out of situations where it would be expected for the last name to come up, to his audience's delight.
302* The first name of ''Radio/TheLoneRanger'' is never revealed, though his last name is known to be Reid.
303[[/folder]]
304
305[[folder:Theatre]]
306* ''Theatre/AvenueQ'': Most characters are only known by their first names, while Mrs. Thistletwat (or Mrs. Butz in the school version) is only known by her last name. The only characters whose full names are known are Kate and Trekkie (who both have "Monster" as their SpeciesSurname, but it's considered racist to assume they're related).
307* In ''[[Theatre/CompanySondheim Company]]'', all the characters are referred to by first name only, as the setting is a gathering of friends who are on a FirstNameBasis.
308* The title character of ''{{Elling}}''. Made all the more curious by the fact that no one mentions it even though everyone refers to his roommate using a FullNameBasis.
309* ''Theatre/LegallyBlonde'': Professor Callahan is never referred to by anything other than his last name.
310[[/folder]]
311
312[[folder:Video Games]]
313* ''VideoGame/AnimalCrossing'': Tom Nook is the only character in the whole franchise to have a given full name; everyone else has unknown surnames. Even then, [[DubNameChange that's only in the localized versions]]; in the original Japanese he's called Tanukichi, playing this trope straight like the rest of the cast. K.K. Slider technically has a first and last name since he prefers to use his stage name, but his real name -- Totakeke -- has no surname either.
314* In the ''VideoGame/{{Borderlands}}'' series, most of the protagonists in the games usually just go by their first name or a nickname, with only a handful of characters so far having full names, from ''VideoGame/BorderlandsThePreSequel'' onwards[[note]]Nisha Kadam, Timothy Lawrence, Aurelia Hammerlock, Zane Flynt, Mozerah "Moze" Andreyevna[[/note]]. Handsome Jack's last name has also never been established, with his company ID in ''VideoGame/BorderlandsThePreSequel'' just listing him as "Jack".
315* In ''VideoGame/CassetteBeasts'', nearly all human characters, including those with the names of historical figures, are only given one name or a nickname. Even the few ones who are given two names, such as Meredith Chen and Levi Lodestein, only reveal their full name in dialogue, while their dialogue box never refers to them by their full name.
316* ''VideoGame/D4DJGroovyMix'': The four members of Abyssmare -- Neo, Sophia, Elsie, and Weronika -- are the only four major characters in the game with no surnames disclosed. Whether they do have surnames that are simply not stated on-screen or they each have OnlyOneName has yet to be confirmed.
317* ''VideoGame/DragaliaLost'': Almost none of the characters have last names, although a special mention goes to the Alberian royal family. They are simply referred to as just that.
318* Until ''VideoGame/DriverSanFrancisco'' gave him the first name John, the protagonist of the ''VideoGame/{{Driver}}'' series was known simply as Tanner. One advertisement for ''Driver 2'' even referred to him as "one cop with one name", and at least one gaming magazine around the time of ''[=DRIV3R=]''[='s=] release gave his first name as Bruce.
319* ''VideoGame/ElseHeartbreak'' has most people referring to themselves and referring to other people by their first names.
320* ''Franchise/FinalFantasy'' has dozens:
321** Characters from [[VideoGame/FinalFantasyII the second game]] only have given names. [[VideoGame/FinalFantasyIII The third entry]] only has them for their main characters, oddly enough.
322** Half of the playable characters in ''VideoGame/FinalFantasyIV''; specifically Rydia, Tellah, and twins Pallom and Porom. [[VideoGame/FinalFantasyIVTheAfterYears The sequel]] has Leonora and Harley.
323** ''Franchise/CompilationOfFinalFantasyVII''
324*** AVALANCHE members Biggs, Wedge, and Jessie. Jessie is [[NamedByTheAdaptation given the surname]] Rasberry in [[VideoGame/FinalFantasyVIIRemake the remake]].
325*** The Turks (Tseng, Reno, Rude, Elena, [[VideoGame/BeforeCrisis Ciss]][[VideoGame/CrisisCore nei]]), though it's implied they're just codenames.
326*** The Shinra executives themselves; Hojo, Scarlett, Heidegger, Palmer, and President Shinra himself. Notable as the President is suceceded by his son Rufus, who is subsequently addressed as President Shinra.
327** ''VideoGame/FinalFantasyVIII'' has Ellone, Raijin, Fujin, Biggs, Wedge, and Dr. Odine. Ellone's adoptive father is surnamed Loire but she's never addressed as such in supplementary materials.
328** Everyone in ''VideoGame/FinalFantasyX'' excpet for Khimari and Seymour, who use their race as a ''de facto'' surname per their world's customs.
329** Possibly in play with ''VideoGame/StrangerOfParadiseFinalFantasyOrigin''. While both the people of Corneria and the Lufenians appear to only have given names, keeping in line with [[VideoGame/FinalFantasyI the original game]], it's revealed late in the story that [[spoiler:most of Jack's party barring Neon are Lufenian agents]]. While [[GivenNameReveal Jack's full name]] ([[spoiler:[[CanonCharacterAllAlong Garland]]]]) would suggest that [[spoiler:at least some of the Lufenians do indeed have surnames]], he's the only member of his group with a known surname. In Jed's case, this may or may not have to do with the fact that [[spoiler:he's implied to be the Lufenian equivalent of a commoner]].
330* ''VideoGame/FullThrottle'': The player character is only ever called just Ben, and prefers to keep his last name a secret. The same goes for Maureen, although you do find out her full name very soon after meeting her: [[spoiler:Maureen Corley.]]
331* None of the characters from ''VideoGame/GhostTrick'' are given two names, thus leaving it unclear in many cases whether people are being referred to by their first name or last name.
332* ''VideoGame/GoingUnder'': Worker humans. Only known surname is of protagonist Jaqueline "Jackie" Fiasco.
333* In ''VideoGame/GrowingUp'', Alicia's the only romanceable character whose last name isn't revealed.
334* ''VideoGame/HeroAndDaughter'': Everyone has only one name, even those summoned from modern setting worlds.
335* Played for fun in ''VideoGame/KingsQuest2015''. The game has a RunningGag where [[TheHero Graham]] tries to introduce himself with his full name, but every time, he gets cut off just as he's about to give his surname. We know it begins with "Cr-" but that's about it.
336* Very few of the characters in ''VideoGame/TheLastOfUs'' and ''VideoGame/TheLastOfUsPartII'' have stated last names. Joel, Tommy, and Sarah's is Miller and Abby’s is Anderson. Ellie's name was Williams in the original draft of the first game before they decided to remove all of them but the Japanese translation decided to use it officially, though WordOfGod would indirectly confirm in a tweet that Williams is indeed Ellie's last name. Isaac's last name is Dixon, as revealed in a document found early on in the second game. Tess' last name is Servopoulos according to her I.D. in the ''Part I'' remake.
337* ''VideoGame/LifeTheGame'': We never find out the last name of Alan, the protagonist's cousin.
338* In the ''VideoGame/MetalGear'' series we have David (Solid Snake), John (Naked Snake/Big Boss), Adamska (Revolver Ocelot), Jack (Raiden), Rosemary, Mei-Ling, Dr. Clark (Para-Medic), Jonathan (two of them), Ed and Johnny (after his surname "Sasaki" was retconned out of existence). That's not even counting characters who are known primarily by their one-word codenames like EVA and Vamp.
339* ''VideoGame/{{Minecraft}}'': The player characters are named Steve (the man) and Alex (the woman) with last names unspecified.
340* ''VideoGame/NoStraightRoads'': Tatiana is the only character with a confirmed last name, with an in-game magazine cover revealing her full name as Tatiana Qwartz. Everyone else either goes by just their first name or a stage name, or is [[NoNameGiven unnamed altogether]] in the case of Yinu's mother and the members of 1010.
341* ''Franchise/{{Pokemon}}'' characters other than Professors rarely have last names (and in the case of Professors, most lack first names). Exceptions include [[VideoGame/PokemonRedAndBlue Daisy Oak, Blue Oak]] (having last names due to being the grandchildren of Professor Oak), and [[VideoGame/PokemonRubyAndSapphire Steven Stone]] from the main series of games, Blake Hall and the rest of the Hall family from ''VideoGame/PokemonRanger: Shadows of Almia'', and Ash Ketchum from [[Anime/PokemonTheSeries the anime]] (who likely only has a last name in the English version [[LipLock to give enough syllables]]).
342* ''VideoGame/{{Portal}}'': The protagonist is named Chell, but her surname is deliberately unknown.
343* ''Franchise/ShinMegamiTensei'':
344** ''VideoGame/ShinMegamiTenseiI'': The Heroine [[HelloInsertNameHere can be given any name in the opening]], but no last name. This turns out to be a plot point: she deliberately doesn't tell her last name to the rebel group she leads, and [[CorruptCop the police]] have no description of her, so they end up arresting any woman that shares the same first name with her even if they are completely innocent, trying to find her by process of elimination.
345** ''VideoGame/ShinMegamiTenseiIV'': Several characters in this game and the sequel ''[[VideoGame/ShinMegamiTenseiIVApocalypse Apocalypse]]'' do not give their surnames. Some characters simply don't have them due to coming from a pseudo-medieval society or being orphans, but there's no reason why Asahi, who has known living relatives in a modern city, shouldn't have one. Just to bring up one example.
346* ''VideoGame/SoUhASpaceshipCrashedInMyYard'': Only the protagonist's first name is known. It's Mark.
347* ''VideoGame/StardewValley'': Nearly everyone in the game is known only by their first name, if any name at all. Two characters have known surnames but not first name: M. Rasmodius, who everyone calls "the Wizard" anyway, and the mysterious Mr. Qi. The only two characters whose full name is revealed are George (Penny calls him Mr. Mullner) and Evelyn (a note in Penny's handwriting calls her Granny Mullner).
348* ''VideoGame/SaintsRow'': Lin, Aisha and Shaundi's surnames were never revealed in the series.
349* ''Franchise/StreetFighter'':
350** With the exception of [[VideoGame/StreetFighterII Edmond Honda and M. Bison]][[labelnote:*]]whose initial stands for either "Mike" or "Master" [[DubNameChange depending on the character bearing the name]][[/labelnote]], the majority of the pre-''[[VideoGame/StreetFighterAlpha Alpha]]'' cast initially had only single names. Ken eventually got a canonical last name of Masters in order to set him apart from [[Franchise/{{Barbie}} a certain other Ken]] once the series started getting some serious merchandizing, while characters introduced later ([[VideoGame/StreetFighterAlpha Dan Hibiki, Sakura Kasugano]], [[VideoGame/StreetFighterIII Sean Matsuda]], [[VideoGame/StreetFighterAlpha Karin Kanzuki, "Rainbow" Mika Nanakawa]], [[VideoGame/StreetFighterIV Juri Han]], [[VideoGame/StreetFighterV Laura Matsuda, Luke Sullivan]], [[VideoGame/StreetFighter6 Kimberly Jackson]], etc.) would have official full names established from the get-go, though they're outnumbered by those without. The [[Film/StreetFighter live-action film]] and [[WesternAnimation/StreetFighter American cartoon]] would give full names to the rest of the ''SFII'' characters (such as Ryu Hoshi, William F. Guile, and Chun-Li [[InconsistentSpelling Z(h)ang/Xiang]]), though that only applies to that particular continuity.
351** [[VideoGame/StreetFighterAlpha Charlie]] is an example that went from being played straight to an aversion by means of AscendedFanon. [[DubNameChange He's known as Nash in Japan]], sparking the theory that Nash was his surname. UDON would adopt this idea for [[ComicBook/StreetFighter their comic adaptation]], though it wasn't until ''VideoGame/StreetFighterIV'' where it became canon, as Guile is shown with Charlie's dog tags which read "Charlie Nash" (thus preventing the animators from needing to redo the cutscene just to tweak Charlie's name between regions). In ''VideoGame/StreetFighterV'', [[LastNameBasis Charlie is almost exclusively referred to as "Nash" regardless of region]] to emphasize his SameCharacterButDifferent and [[spoiler:CameBackWrong]] status, though certain characters (like Guile) remain on a FirstNameBasis with him.
352** An ambiguous example comes from Yun and Yang, introduced in the ''VideoGame/StreetFighterIII'' series. Together, they are often referred to as the Lee Brothers, as they are the nephews of Lee from [[VideoGame/StreetFighterI the first game]]. Officially, it's never been stated whether their surname actually is Lee, not unlike the ongoing confusion regarding [[Franchise/SuperMarioBros the Mario Bros.]]
353** Barring Rolento, Hugo/Andore, and Maki, most of the ''VideoGame/FinalFight'' cast that was [[{{Transplant}} carried over]] to ''Street Fighter'' have no known surnames. ''VideoGame/StreetFighterV: Arcade Edition'', however, marks one of the few times Cody's full name (Cody Travers) has been mentioned outside of ''[[CanonDiscontinuity Streetwise]]'' and similarly canonized Lucia's long-rumored surname of "Morgan."
354* ''VideoGame/StoryOfSeasons'': Pete, Sara, Rachel, Sanjay, Rod, Nami, Chelsea, Georgia... The list goes on. Most characters have only given names, even the doctors and mayors.
355* Try naming five characters in the ''Franchise/SuperMarioBros'' universe that have known full names. We'll wait (although it's worth noting that Mario and Luigi’s last name is hinted to be, in fact, [[RepetitiveName Mario]]. They ''are'' called the Mario Bros. after all).
356* While everybody in ''VideoGame/SurvivorFire'' has the surname of [=MacDougal=], their first names are a mystery.
357* ''Franchise/{{Tekken}}'': Hwoarang's full name is never revealed. Not played straight with Ganryu, King, Raven, as those are [[OnlyKnownByTheirNickname mere pseudonyms]] (Ganryu and King are ring names, while Raven is an agent name).
358* ''VideoGame/TrickAndTreat'': Charlotte, John, and Richard are somewhat human, but we don't know their surnames, and it's a world with at least somewhat modern technology, as seen in its prequel, ''VideoGame/TheWitchesTeaParty''.
359* ''VideoGame/AVeryLongRopeToTheTopOfTheSky'': According to WordOfGod, they exist, but none are ever said except for the only known marriage of Gainer's parents.
360* ''VideoGame/TheWalkingDead'': Clementine's surname is never revealed throughout the series. This is very strange considering the setting, at least someone should have asked her about it or Clementine herself should have told someone. It's doubtful that we'll ever learn what it is. It might be Marsh; one of the calls on the answering machine does mention the "Marsh Household". Developers have stated that her surname was originally "Crawford", before a community under that name was created in episode four of the first season.
361* ''VideoGame/XenobladeChronicles'': Throughout the series, surnames are a rarity.
362** ''VideoGame/XenobladeChronicles1'': Melia Antiqua and her family are the only characters with surnames; considering they're royalty, it makes sense that they're the ones that would consider their surnames important. Shulk is an orphan, so he could well not have a surname at all, but most of the other characters presumably just don't bother mentioning them. In particular, the BigBad, Zanza [[spoiler:was originally a human man named Professor Klaus. "Klaus" is, by all indications, his given name, but his surname is never mentioned]].
363** ''VideoGame/XenobladeChronicles2'': Rex is an orphan, so there's no reason to assume he has a surname, and quite a few of the other characters are [[ArtificialHuman Blades]], who ''definitely'' don't have surnames. The only explicit exceptions are royalty: Zeke von Genbu is the prince of Tantal, and Mòrag Ladair is the cousin to Niall Ardanach, emperor of Mor Ardain. There's also a very easy to miss bit of dialogue that Nia is actually Nia Echell, [[spoiler:the adopted daughter of Lord Echell, as she is the Flesh Eater Blade used to try to heal his daughter]].
364** ''VideoGame/XenobladeChronicles3'': None of the soldiers have surnames, since they're [[BornAsAnAdult born at age ten]] [[UterineReplicator from growth acceleration pods]] [[TeenageWasteland and then die ten years later]]. None of them know what families ''are'', much less why you'd have an extra name. Surnames still seem rare among the City people, who do know what families are; it seems that only the descendants of the six Founders have surnames. In ''[[VideoGame/XenobladeChronicles3FutureRedeemed Future Redeemed]]'', we meet those Founders, and even they don't use their surnames. It's unclear if they invented those surnames at a later date, if they inherited them from their parents (who didn't have surnames in previous games), or if they got them from their spouses. Matthew does confirm that his name is Matthew Vandham at the end, which presumably came from his beloved grandfather. But since his grandfather was the child of two soldiers without surnames, it's still unclear where the name came from in the first place.
365* ''VideoGame/ZanZarahTheHiddenPortal'': The proganist is a human from Earth who ''should'' have a last name, but she is only known as Amy.

369* ''Webcomic/TheAdventuresOfDrMcNinja'': Dr [=McNinja=]'s surname is explicitly stated multiple times throughout the series as [=McNinja=], but no first name is given. He's usually just called "Doctor", and his clone goes by Old, as in Old [=McNinja=]. In "[[WholeEpisodeFlashback First Generation Ninja American]]", we find out why no first name has been given: [[spoiler:his grandpa erased his name from history to [[SealedEvilInACan trap a]] [[NinjaPirateZombieRobot ghost wizard]] who was trying to cast a curse that would make him an [[CosmicPlaything enemy of the universe itself]], and saying his name will cause the ghost wizard to be freed. He is ultimately forced to give up his name in order to persuade Sparklelord to stop King Radical from causing TheEndOfTheWorldAsWeKnowIt, and his name is revealed to be "Patrick".]]
370* ''Webcomic/DarthsAndDroids'': All the players are on FirstNameBasis with each other, and their surnames are never mentioned.
371* ''Webcomic/ElGoonishShive'' didn't reveal Sarah's last name (Brown) until 2007 (having been running since 2002). When they ''did'' give Sarah's name, it was a casual toss-out (the principal was yelling at her).
372* Jenny from ''Webcomic/JennyAndTheMultiverse'', in contrast to her love interest Laura Drake.
373* ''Webcomic/ThePetriDish'': Downplayed for Thaddeus's mother Betty. We don't know her surname, but it could well be "Euphemism", since that's her son's last name.
374* In ''[[WebComic/{{PHD}} Piled Higher and Deeper]]'', several of the characters do not have last names.
375* ''Webcomic/QueenOfWands'' never mentions the last names of its characters. Kestrel from ''[=QoW=]'' wound up becoming a recurring character in ''Webcomic/SomethingPositive'' (which ''does'' have characters with full names) but still has no last name, which is [[LampshadeHanging Lampshaded]] on the cast page.
376* Sabrina and her family in ''WebComic/SabrinaOnline'' never had their surname revealed. Lampshaded when Sabrina married R.C. near the end of the strip's run; the first time she was introduced as "Mrs. Conrad", another character remarked "Oh... so ''that's'' her last name!".
377* ''Webcomic/{{Unsounded}}'': Elka is the only member of the main cast whose full name remains a mystery, even with the final chapter well under way. Emil Toma is the only character who knows her full name, but given their positions working together keeps to a LastNameBasis with her.

381* ''Literature/CanYouSpareAQuarter'': We never get to know what the protagonist Jamie's family name is.
382* The only characters whose full names have been mentioned in ''Animation/FengLingYuXiu'' are Bai Yuxiu, Chen Feiyan, who [[TheGhost has yet to make an onscreen appearance]], and some members of a performing troupe who serve as minor antagonists.
383* ''WebVideo/KateModern'': Several major characters' surnames have not been revealed, including Charlie, Lauren, Sophie and Terrence.
384* ''WebVideo/MarbleHornets'': Alex Kralie is the only character with a known last name. The one time Jay (the narrator) mentions his last name to someone, he mutes it on the Youtube video. When he finds some medical records of Tim's, someone has scribbled over ''his'' last name except for the first letter (W). Their names are eventually revealed in the DVD credits: Jay (Merrick), Tim (Wright), Brian (Thomas), Jessica (Locke), Seth (Wilson), Amy (Walters) and Sarah (Reid).
385* Michael and Martin from ''WebVideo/Needlem0use'' do not have their last names revealed due to plot irrelevance. Seeing as how the series ended in late 2022, they may never be revealed at all.
386* ''WebAnimation/SimonsCat'': Simon's surname is unspecified, though the creator, who [[AuthorAvatar Simon was based on]], has the last name of "Tofield".
387* Corbin and Desmond from ''WebVideo/SplinterCellExtinction''. Desmond's surname is always left out of the frame, and "Corbin" is either the protagonist's given name or code name (judging from the fact he's apparently on FirstNameBasis with his MissionControl).
