A 2000-2002 three-season web animation series of 30 short episodes made by Noodle Soup Productions for Warner Brothers Animation and created by Paul Dini and Hilary J. Bader, Gotham Girls stars the female characters of the Gotham setting: Poison Ivy, Harley Quinn, Catwoman, and Batgirl, with occasional appearances by Zatanna and Renee Montoya. The series is notable for featuring the characters' television voice actresses and is generally considered canon with the DCAU.
The first twenty episodes (released monthly) were unrelated comedic interludes featuring tales of the daily life of the characters. The third season of ten episodes formed an interconnected arc concerning the disappearance of all men from Gotham City. Some installments featured an interactive element or mini-game.
The Flash Animation (hailing as it did from the early days of the web) was not very fluid, but got better as time went on.
The episodes are still online, though hidden on the Warner Brothers website, and a full list of the episode links can be found on the Other Wiki and YouTube. The entire series was also included as Bonus Content on the Birds of Prey television series DVD. A spinoff comic book was released for the series, and Paul Dini's "Harley and Ivy" mini-series and later Gotham City Sirens clearly took some inspiration from the premise.
- Anti-Villain: Invoked in-universed. Ivy calls herself an "eco-terrorist of global importance". Which means she makes a contribution. At least one episode has her going out of her way to get the mayor to prevent bulldozing of a park because he swore he wouldn't in his election campaign.
- Beauty Contest: Batgirl stages one in order to catch the villains. No beauty is actually judged, given the feminist vibe.
- Breakout Character: The entire show was pretty much made to capitalize on fandom love for Harley Quinn.
- Check, Please!: Used (incorrectly) by Harley in Strategery.
- Curse Cut Short:
Batgirl: Long life my aAAGH! [Said just as the ledge she was holding collapses.]
- Derailed Fairy Tale: The Three Babes.
- Fountain of Youth: Happens to Harley in one episode.

- Nice Hat: Zatanna. "Sorry, boys. No-one touches the hat."
