The Mickey Mouse universe is a fictional shared universe which is the setting for stories involving Disney cartoon characters Mickey and Minnie Mouse, Pluto, and many other characters. The universe originated from the Mickey Mouse animated short films produced by Disney starting in 1928, but its first consistent version was created by Floyd Gottfredson in the Mickey Mouse newspaper comic strip. Real-world versions also exist in Disneyland and Tokyo Disneyland, called Mickey's Toontown.

Since 1990, the actual city in which Mickey lives is typically called Mouseton, and is often depicted as the city next to Duckburg, the city in which Donald Duck lives. (See Donald Duck universe) According to traditional continuity, both cities are located in the fictional U.S. state of Calisota – analogous to Northern California. Other characters, like Goofy and Pete, are shown living in fictional towns such as Spoonerville in Ohio.

The most consistent aspect of the Mickey Mouse universe is the characters. The most well-known include Mickey's girlfriend Minnie, pet dog Pluto, friends Horace Horsecollar, Clarabelle Cow, Donald Duck, Daisy Duck and Goofy, and nemesis Pete. Some Disney productions incorporate characters from Disney's animated feature films, such as Bath Day (1946; in which Figaro from Pinocchio appears as Minnie's cat), Mickey's Christmas Carol (1983), and – most extensively – Disney's House of Mouse (2001–2003).
