The last episode or episodes of a season, consisting of a story which ties up most of that season's loose ends and aims to be as dramatic as possible. They may be The Climax of an ongoing Story Arc, or simply a new story, the most dramatic yet. They may kill off main characters, bring back villains from earlier in the series, and set up the next season. Cliffhanger endings are common.
Season finales are pretty much guaranteed to draw in large audience figures.
While this is by no means universal, it's still very common. A more recent phenomenon has been the mid-season or winter finale — where networks hype the final episode before a mid-season hiatus in a similar manner.
Of course, when the show is ending for good, they really pull out all the stops.
See "What Now?" Ending, Series Fauxnale, Cliffhanger and Dénouement Episode for specific varieties of Season Finale.

- Act 1: The main character's neighborhood is hit by a meteor, with him escaping just in the nick of time.
- Act 2: It's revealed that the desert a secondary character is wandering around on is post-apocalypse Earth. Meanwhile, Rose's mother opens a secret doorway that leads to a nearby laboratory, and Dave prepares to fight his brother.
- Act 3: Rose finally enters the Medium. Jade gets her hands on the SBURB discs, which turn out to somehow be Dave's copy, hidden in a time capsule, and John finally goes through his first gate.
- Intermission: The Midnight Crew Intermission is canon, and it turns out Slick is Karkat's exile.
- Act 4: Jack slaughters WV's army and starts the Reckoning weeks ahead of schedule. He then wrecks Prospit, sending its moon plummeting to the Battlefield below. Dream Jade throws Dream John out of the way, but is too late to escape the blast radius herself and is killed, causing her dreambot to explode and the real Jade to fall from her bedroom. The resulting chaos wakes Dream John up. Finally, Rose decides she's had enough of destiny and blows up her first gate. And that's not even getting into what happens in between acts 4 and 5.
- Act 5 Act 1: The kids activated a rift called the Scratch, which somehow sent an unstoppable demon into the troll's universe. This meant that they were unable to claim their ultimate reward for completing SGRUB: entry into the kid's universe, which they had CREATED.

He's finally released 413 million years later on post-apocalyptic Earth, ten seconds after the White King is. He murders WK, WQ, and AR, and mortally wounds WV in order to get the uranium from his stomach. He then uses the uranium to power a transportalizer in WV's station, which sends him to the trolls' universe and allows him to destroy their Prospit, Derse and Lands, as well as kill all of the Trolls' dream selves. Finally, Jack uses Red Miles to attack the Genesis Frog representing Earth's universe.
- Piloting Derse's moon through the Furthest Ring using a map Dave drew, Rose and Dave are surprised to find that the Green Sun isn't where it should be. Undaunted, they take the Tumor to a crypt in the center of the moon, where their Quest Beds await. They set up the Tumor, and it opens up to reveal ectobiological equipment, with Earth's universe on one side and Alternia's on the other. As Jack's Red Miles ravage Earth's universe, Spades Slick finally kills Snowman, ending Alternia's universe as well.
- Jadesprite and Davesprite are about to be obliterated on the Battlefield when Jade and Jadesprite merge to become God Tier Jade, with Witch of Space powers, Bec's reality-warping powers, and a sprite's knowledge of the game. She then shrinks the meteor to the size of a baseball, and using her new-found powers, enlarges a battleship, and shrinks the Battlefield, LOWAS, LOLAR, LOHAC, and LOFAF, picking up John along the way. On Earth, PM witnesses the approaching Red Miles. She finds the White Queen's Ring, which WV had had the whole time.

Finally, as the Critical Moment approaches, a dying Doc Scratch takes a moment to send a final message to Gamzee, informing them that they are all suckers.

- Act 6 Intermission 1: Prototyped PM heads for the Green Sun at top speed, in pursuit of Jack, who is in turn pursuing the trolls, Rose and Dave. Dreaming on Prospit, Jane sees visions of things to come in the Skaian clouds, including Imperial Drones bearing the Condesce's sigil, Roxy Lalonde (Rose's Mom's post-Scratch incarnation) hurling a cat through a Fourth Wall, and Jake English (Grandpa's post-Scratch version) on his island as the volcano there erupts. Jane witnesses the miracle of a new beginning, but is stabgreeted by post-scratch Jack Noir, who absconds just as Jane is about to do a "lifey thing".
- Act 6 Act 2: As a meteor quickly approaches her house on Earth, Jane does all the setup she needs to enter the Medium, but is confused when her Cruxite Artifact never appears. The countdown ends, and she enters anyway, but as she does, she gets a glimpse of what the "meteor" really is — Her Imperious Condescension's flagship. Years in the future — but not many — we see a flooded Earth where Troll society has been rebuilt under the Condesce's rule, with humans and Dersites apparently reduced to struggling minorities. It is further revealed that Roxy and Dirk have been living in this time all along, as they prepare to fight hordes of Imperial Drones. Meanwhile, back in the past, Jake has descended into the Frog Temple for reasons that aren't further elaborated on.
- Act 6 Act 3: Dirk and Jake are knocked out and Jane and Roxy are both killed.

After a brief confrontation, the portal opens to reveal a man resembling Grunkle Stan: the author of the journals, Grunkle Stan's identical twin brother.
- The second season has a four-parter series finale "Weirdmageddon", which manages to completely outdo the first season finale as Bill Cipher takes over Gravity Falls using his new powers and friends from his home dimension. In the climax, the cornered Stan twins trick Bill into going into Grunkle Stan's mindscape. He is then finished off by a left hook by Grunkle Stan after some pleading from Bill.
- The Legend of Korra has BIG two-parters for the end of each Season, featuring things like Korra's Bending being taken by Amon, who turned out to be Tarrlok's brother, before getting it restored by Aang; a massive Kaiju-esque battle against Unalaq the Dark Avatar; the near-end of the Avatar cycle at the hands of Zaheer, and most spectacularly the Grand Finale, Day of the Colossus/The Last Stand, in which Team Avatar battles against Kuvira's giant robot in a no-holds-barred showdown that leaves Republic City leveled, Hiroshi sacrifices himself and Mako nearly does the same, Korra creates a new Spirit Portal in the process of saving Kuvira from her own out-of-control weapon, and Korra and Asami get a Relationship Upgrade. Wow.
- My Little Pony: Friendship Is Magic:
- The first season finale, "The Best Night Ever", features the main characters attending the Grand Galloping Gala, which has been built up in several previous episodes as the biggest social event in Equestria, only to be disappointed in various ways.
- The second season finale, "A Canterlot Wedding", blows the first season finale out of the water in terms of excitement. It's a two-parter that revolves around central character Twilight Sparkle's brother getting married to royalty, and features an evil shape-shifting Emotion Eater impersonating the bride and hypnotizing the groom, a huge fight between the Mane Six and an army of mooks, and a climax that involves a force-field bolstered by The Power of Love.
- The third season finale, "Magical Mystery Cure", is a Musical Episode revolving around Twilight accidentally switching the cutie marks and destinies of her friends, ruining their lives. This gets resolved by the end of the second act, but sets up a stunning third act, wherein Twilight fulfills her own destiny by becoming an alicorn, and is then crowned as Equestria's newest princess.
- The fourth season finale, "Twilight's Kingdom", like the season 2 finale is a two-parter. They deal with the escape of Lord Tirek — possibly the most terrifying villain in the franchise — and the attempts to defeat him. Which involves, among other things, Twilight being granted the power of all the other Princesses and engaging in the single most impressive fight sequence in the show's history, the Golden Oaks Library being completely destroyed, Tirek ultimately only being defeated when the Mane Six unlock the box they got from the Tree of Harmony and gaining Rainbow Power, and finally, Twilight gaining her own castle and being declared the Princess of Friendship.
- The fifth season finale, "The Cutie Remark", is another two-parter. Starlight Glimmer, the villain of the season's two-part opener, returns and enacts a plot to go back in time and prevent Rainbow Dash from having her first Sonic Rainboom, thus keeping the Mane Six from earning the specific cutie marks that led to them coming together as the heroes we know and love, and Twilight trying to stop her from doing so. After this results in a series of increasingly dark Bad Future Alternate Timelines, Twilight ends the conflict by prompting a Heel Realization and subsequent Heel–Face Turn in Starlight, who undoes the damage to history and restores things to normal.
- The sixth season finale, "To Where And Back Again", is yet another two-parter. Queen Chrysalis and the Changelings return and kidnap the Mane Six, the Princesses, and Shining Armor as part of a plan of taking over all of Equestria. To stop them, a group of secondary characters — Starlight, Trixie, Discord, and Thorax — team up to infiltrate the Changeling hive and rescue the heroes. It ends with Thorax becoming the new King of the Changelings, sharing love to bring about a Heel–Race Turn among his kind, forcing Chrysalis to flee, swearing revenge.
- The seventh season finale, "Shadow Play", is once more a two-parter. Twilight and her friends succeed in releasing the Pillars of Harmony from their imprisonment in limbo, but in the process also unleash the Pony of Shadows. The Mane Six then have to work with the Pillars to defeat the Pony of Shadows until Starlight realizes that it's actually the Pillars' friend Stygian, who was consumed by darkness from trying to help his friends. Realizing this, they work together to return him to normal. Also, the Sirens from the second Equestria Girls movie make an appearance.
- The eighth season finale, "School Raze" is, yet again, a two-parter. Cozy Glow, working with the assistance of Tirek, sets in motion a plan to imprison the Mane Six and take over the School of Friendship. It is then up to the six main students to work together to stop her.
- The ninth season ends with the series' Grand Finale, starting with another two-parter, "The Ending of the End", wherein the heroes face off in a Final Battle with the Legion of Doom composed of all the remaining Big Bads. This is followed by the Distant Finale episode, "The Last Problem", which shows what's become of all the main character years into Twilight's reign over Equestria.
- Episode 26 of Scooby-Doo! Mystery Incorporated is the season finale and it ends in a cliffhanger. The gang has been fragmented by the revelation that Fred's dad, the Mayor of Crystal Cove was the Big Bad all along and isn't his real dad, so he's broken the gang up to find who he really is. Meanwhile, his engagement to Daphne is now in indefinite abeyance, Shaggy is being sent to military school, Scooby is being sent to a farm, Daphne is taken home to wallow in misery and Velma is taken home to stew about not coming clean to her friends about who Angel Dynamite really is.
- The Simpsons did this deliberately as a publicity stunt in 1995: the series' firstnote Multi-Part Episode was the famous Who Shot Mr. Burns? arc, which ended the sixth season in May. The following summer was dedicated to a FOX-promoted contest where fans attempted to guess the identity and motive of the would-be assassin for a chance at a Contest Winner Cameo (or cash prize). There was even attempt by the production staff to leak Foiler Footage to throw media outlets off the scent. By September, the contest ended and the mystery was revealed for the seventh season premiere episode.
