Pete (also called Peg Leg Pete, Bad Pete and Black Pete, among other names) is a cartoon character created by Walt Disney and Ub Iwerks of The Walt Disney Company. Pete is traditionally depicted as the villainous arch-nemesis of Mickey Mouse, and was made notorious for his repeated attempts to kidnap Minnie Mouse. Pete is the oldest continuing Disney character, having debuted in the cartoon Alice Solves the Puzzle in 1925. He originally bore the appearance of an anthropomorphic bear, but with the advent of Mickey in 1928, he was defined as a cat.

Pete appeared in 67 animated short films between 1925 and 1954, having been featured in the Alice Comedies and Oswald the Lucky Rabbit cartoons, and later in the Mickey Mouse, Donald Duck, and Goofy cartoons. During World War II, he played the long-suffering sergeant trying to make a soldier out of Donald Duck in a series of animated shorts.

Pete's final appearance during this era was The Lone Chipmunks (1954), which was the final installment of a three-part Chip 'n' Dale series. He also appeared in the featurettes Mickey's Christmas Carol (1983) and The Prince and the Pauper (1990), the feature films A Goofy Movie (1995), Mickey's Once Upon a Christmas (1999), and Mickey, Donald, Goofy: The Three Musketeers (2004), and the short film Get a Horse! (2013).

Pete has also made many appearances in Disney comics. He appeared as Sylvester Shyster's dimwitted sidekick in the early Mickey Mouse comic strips before evolving into the main antagonist. In the Italian comics production he has been given a girlfriend, Trudy, and has come to be the central character in some stories. Pete later made several appearances in television, most extensively in Goof Troop (1992–1993) where he was given a different continuity, having a family and a regular job as a used car salesman and being a friend (albeit a poor one) to Goofy. He reprises this incarnation in 1999's Mickey's Once Upon a Christmas. Pete also appears in House of Mouse (2001–2003) as the greedy property owner who is always trying to exploit devious ways and loopholes to get the club shut down.

Although Pete is often typecast as a villain, he has shown great versatility within the role, playing everything from a hardened criminal (The Dognapper, The Lone Chipmunks and most of his depictions in comics) to a legitimate authority figure (Moving Day, Donald Gets Drafted, Mr. Mouse Takes a Trip), and from a menacing trouble maker (Building a Building, Trombone Trouble) to a victim of mischief himself (Timber, The Vanishing Private). On some occasions, Pete has even played a sympathetic character, all the while maintaining his underlying menacing nature (Symphony Hour, How to Be a Detective). In the animated TV series Mickey Mouse Clubhouse, which is aimed at preschoolers, he is largely a friendly character, although his antics can occasionally prove an annoyance.
