Mickey Mouse II (released as Mickey Mouse in Europe) is a 1991 action/puzzle video game released by Kemco for the Nintendo Game Boy in Japan and Europe. It is the sequel to Mickey Mouse, and the second game in Kemco's series of video games starring Mickey Mouse.

Due to Capcom holding the rights to make Disney video games on Nintendo systems in the US at the time, when the game was to be released in the US, Kemco replaced the Disney characters in the game with Looney Tunes characters and renamed it The Bugs Bunny Crazy Castle 2.
