Thru the Mirror is a 1936 American animated short film directed by David Hand from a story by William Cottrell and Joe Grant. In this cartoon short, Mickey Mouse has a Through the Looking-Glass-parody-like dream that he travels through his mirror and enters a topsy-turvy world where everything is alive. While there, he engages in a Fred Astaire dance number with a pair of gloves and a pack of cards, until the cards chase him out of the bizarre world. Produced by Walt Disney Productions and released by United Artists, it was the 83rd Mickey Mouse short film to be released, the fourth of that year.

The title is written as Thru the Mirror on the title card, but the alternative spelling Through the Mirror is used on the poster for the film.
