Private Snafu is the title character of a series of black-and-white American instructional adult animated shorts, ironic and humorous in tone, that were produced between 1943 and 1945 during World War II. The films were designed to instruct service personnel about security, proper sanitation habits, booby traps and other military subjects, and to improve troop morale. Primarily, they demonstrate the negative consequences of doing things wrong. The main character’s name is a play on the military slang acronym SNAFU, “Situation Normal: All Fucked Up”. The cleaned-up version of that phrase, usually used on radio and in print, was “Situation Normal: All Fouled Up”.

The series was directed by Chuck Jones and other prominent Hollywood animators, and the voice of Private Snafu was performed by Mel Blanc.
