The Mickey Mouse universe is a fictional shared universe which is the setting for stories involving Disney cartoon characters, including Mickey and Minnie Mouse, Donald and Daisy Duck, Goofy and Pluto as the primary members (colloquially known as the "Sensational Six"), and many other characters related to them, most of them being anthropomorphic animals. The universe originated from the Mickey Mouse animated short films produced by Disney starting in 1928, although 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. The term "Mickey Mouse universe" is not officially used by The Walt Disney Company, but it has been used by Disney comics author and animation historian David Gerstein. The Walt Disney Company typically uses terms such as Mickey & Friends or Mickey & the Gang to refer to the character franchise.
Since 1990, the city in which Mickey lives is typically called Mouseton in American comics. In modern continuity, Mouseton is often depicted as being located in the fictional U.S. state of Calisota, analogous to Northern California. This fictional state was invented by comics writer Carl Barks in 1952 as the location for Donald Duck's home city, Duckburg.
