Catwoman is a fictional character associated with DC Comics' Batman franchise. She was created by Bill Finger and Bob Kane, partially inspired by Kane's second cousin by marriage, Ruth Steel.

The original and most widely known Catwoman, Selina Kyle, first appeared in Batman #1 (Spring 1940) in which she was known as The Cat. As an adversary of Batman, she was a whip-carrying burglar with a taste for high stake thefts. Modern writers have attributed her activities and costumed identity as a response to a history of abuse.

Since the 1990s, Catwoman has been featured in an eponymous series that cast her as an anti-heroine rather than a supervillainess. The character has been one of Batman's most enduring love interests, and has occasionally been depicted as his one true love.

A popular figure, Catwoman has been featured in most media adaptations related to Batman. Actresses Julie Newmar, Lee Meriwether, and Eartha Kitt introduced her to a large audience on the 1960s Batman television series. Michelle Pfeiffer portrayed the character in 1992's popular film Batman Returns. Halle Berry starred in a stand-alone Catwoman film in 2004, although the film features a title character bearing little resemblance to the comic book character. Catwoman is #51 on Wizard magazine's "100 Greatest Villains of All Time" list.
