In 100 Things to Do Before High School, the Black Lipstick Girls are a clique of goth girls who seem to scare the other students (and some staff) just by existing. CJ briefly joins them in "Change Your Look and See What Happens Thing!"
Tommy: "Death signed my yearbook. 'Have a good summer,' he wrote, 'see ya next year.' And then I noticed it wasn't my yearbook he signed, it was my tombstone." Lorna: What d'you think? Tommy: [lying] I like it. I especially like the surprise ending here. Lorna: You're the first one to get the irony.
The Addams Family: Morticia and Wednesday were Goth before the scene existed. The whole concept of the show, to contemporary viewers, is a comedy about a family of bohemian arty goths in stereotypical white-picket-fence suburbia (although Fester is more of a rivethead).
The Big Bang Theory has the episode "The Gothowitz Deviation" featuring Howard and Raj attempting to dress as Goths, in order to date one from a local Goth Bar. At first it went fairly well, but it quickly went downhill when both were too nerdy at heart to keep up their disguises.
Merton J. Dingle from Big Wolf on Campus was a rather pathetic, but strangely endearing simulacrum of a goth.
Apparently, nobody told him that you can be a goth and a nerd at the same time.
The Blood Ties (2007) TV show has Coreen, a fairly well adjusted goth, as assistant to the main character Vicki. She even has an episode where she gets Vicki to solve murders at her goth club.

In the season five episode "The Performer," several goth girls are murdered, and the team believes the killer may be a singer who caters to a largely goth crowd. It's actually his completely non-goth manager, aided by a schizophrenic goth fan.
A suspicious goth was featured in "Risky Business," and he had good reason to be an Emo TeenHis chainlink choker was to hide the fact that he was constantly strangled to unconsciousness by his sadistic, Munchhausen-by-proxy/paramedic dad, who also killed his mom.
Dates: Kate has the look, complete with all of her actress's piercings and Raven Hair, Ivory Skin. She wears dark clothing including leather, with her hair pulled back in a style that resembles a mohawk too.
Deadly Class: Petra dresses the part, with dyed black hair, black lipstick and mostly black clothes, at least until she has a mental breakdown. Then again after she finally fights Brandy and leaves the student council.
Ellie Nash (until season 5), Ashley Kerwin (in season 2 only), Jane Vaughn, and Eli Goldsworthy from Degrassi.

Nadine from Girls In Love was normally a gloomy goth, although she would occasionally slip into Perky Goth territory depending on what was happening in her private life.
The main character of The Haunting HourMade-for-TV Movie. At one point in the movie, she sat in her room and listen to depressing music all day long. The reason? Well, she dropped food on herself at school. Oh, the inanity!
Later, when she's asked to take her brother trick or treating, she sulks while the soundtrack plays:
Walking down the street alone. Everything I've ever loved is gone, gone, gone...
Mark, the youngest son, adopted a goth look during the seventh season, complete with all black clothes, a spiky haircut and (briefly) wearing black nail polish and lipstick. This was eventually done away with during the eighth and final season, however.
There was an episode where the family's at a poetry reading for Wilson, and a goth girl goes up to read/recite her poetry:
Richmond from The IT Crowd is either a parody of actual goths or (more likely, given his portrayal by pop culture barometer Noel Fielding) a parody of the goth stereotypes listed above.
Kamen Rider Ex-Aid has the tertiary rider, Taiga Hanaya/Kamen Rider Snipe as one, who has black and white hair and is rather unpleasant with everybody else.
Kamen Rider Fourze features a psychic goth girl as one of the protagonists.
One of her flashback episodes portrays Lost's Claire as a goth teen.
Alex experiments with a goth-influenced look under the brief influence of a goth friend in the fourth-season Modern Family episode "Snip".
Parodied on Saturday Night Live's recurring "Goth Talk" sketch, starring Chris Kattan as Azrael Abyss, Prince of Sorrows, and Molly Shannon as Circe Nightshade. The show's sponsor was a store called "The Gloom Room"... "It's an orgy of the macabre... Located right next to the Pizza Hut on Hibiscus Road." The two would discuss various topics relating to the subculture, only to be interrupted by things that would remind the viewers that Todd and Stephanie (their real names) are really just dorky teens who live mundane suburban lives and are in no way dark or sinister.
One episode of This is Wonderland had Elliot defending a goth man who had gotten into a fight with a car dealer who had made fun of him. The goth character was treated much more sympathetically than it sounds, and the judge eventually agreed that the provocation was sufficient. Along the way, they commented upon the unfair stereotypes associated therewith. Elliot even went goth for a few episodes.
Stranger Things: Eden is very clearly not sticking with her Mormon parents ideals, showing her individuality through her goth clothing before her full rejection of Mormonism is confirmed when she gets high with Argyle.

Many of the vampires in True Blood fit the goth stereotype — not to mention the vampire bar "Fangtasia" is essentially a "goth-bar," with practically every single patron fitting this trope. The setting, theme and even the music playing at the bar further contribute to the gothic stereotyping in the show.
An ep of Two of a Kind sees one of the Olsen twins befriending a goth... Played by Helga Pataki's voice actress. Replete with dark hair, pale skin, black outfit, nose ring, and love of Heavy Metal (about a CD by her favorite band "Human Sacrifice:" "Don't let the name fool you, they do a good thrash version of You Light Up My Life" [insert Laugh Track here]). And when the other Olsen twin offers to buy her a new backpack (long story), guess what color backpack she offers to buy her?
