The Mickey Mouse Universe (not an official term used by the Walt Disney Company) is the setting where Mickey Mouse and the characters associated with him live. Characters in this universe use many Ajax brand products, similar to Looney Tunes and other Warner Brothers characters using Acme products. The city they live in is called Mouseton, according to the comic books under the Disney Comics Imprint.
