Stop That Tank! (aka Boys Anti-Tank Rifle) is a 22-minute 1942 instructional film created during World War II by Walt Disney Productions for the Directorate of Military Training, The Department of National Defence and the National Film Board of Canada (NFB). Its purpose, akin to "edutainment", was to instruct Canadian soldiers in the handling and care of the Boys Mk.1 Anti-tank rifle for use in combat against Nazi tanks. The film presented information in an entertaining manner as well as providing an anti-Nazi propaganda message.

Stop That Tank! is organized into two separate sections: the first animated section lasting three minutes, 15 seconds is a comedic demonstration of the anti-tank gun in an anti-Nazi propaganda "sketch", while the second longer section uses both cartoon animation and live action sequences to demonstrate proper use and handling of the Mk.1 Boys Anti-Tank Rifle.
