Stage Door Canteen is a 1943 American World War II film with musical numbers and other entertainment interspersed with dramatic scenes by a largely unknown cast. The film was produced by Sol Lesser's Principal Artists Productions and directed by Frank Borzage. The film features many celebrity cameo appearances but primarily relates a simple drama set in the famed New York City restaurant and nightclub for American and Allied servicemen. Six bands are featured. The score and the original song, "We Mustn't Say Goodbye", were nominated for Academy Awards.

Stage Door Canteen is in the public domain in North America and for this reason is widely available in many DVD and VHS releases of varying quality.
