The Yankee Doodle Mouse is a 1943 American one-reel animated cartoon in Technicolor. It is the eleventh Tom and Jerry short produced by Fred Quimby, and directed by William Hanna and Joseph Barbera, with musical supervision by Scott Bradley and animation by Irven Spence, Pete Burness, Kenneth Muse and George Gordon. Jack Zander was credited on the original print, but his credit was omitted in the 1950 reissue. It was released to theaters on June 26, 1943 by Metro-Goldwyn Mayer.

The short features Tom the cat and Jerry the mouse chasing each other in a pseudo-warfare style, and makes numerous references to World War II technology such as jeeps and dive bombers, represented by clever uses of common household items. The Yankee Doodle Mouse won the 1943 Oscar for Best Animated Short Film, making it the first of seven Tom and Jerry cartoons to receive this distinction.

This is the first Tom and Jerry short to be animated by Ray Patterson, who arrived from Screen Gems. Patterson would continue to work for Hanna and Barbera until the 1980s.
