Tanks a Million is a 1941 American comedy film film directed by Fred Guiol. It was the first of Hal Roach's Streamliners, short films under an hour designed for the lower half of a double feature. The two leading characters, whiz-kid sergeant Doubleday (played by William Tracy) and his rival Sergeant Ames (Joe Sawyer), would go on to feature in seven more films, though the series has no overall title.

Despite the title and military setting, no tanks are seen in the film.
