The Gorilla Mystery is a black and white Mickey Mouse cartoon released to theaters on October 10, 1930.
Mickey is reading a newspaper that says a man-killing gorilla has escaped from the zoo, and all citizens are warned to lock their doors. Mickey panics and calls Minnie to tell her the news. Minnie, however, is not afraid and plays a song on the piano to show it. However, the gorilla enters her home and kidnaps her. Mickey hears Minnie screaming and determines that it must have been the gorilla, so he races to her house to save her.
- The horror theme of the short was inspired by an earlier Mickey Mouse short, The Haunted House.
- The short later inspired another short years later with the same plot, but with Donald Duck as the star.
