Star Spangled Rhythm is a 1942 American all-star cast musical film made by Paramount Pictures during World War II as a morale booster. Many of the Hollywood studios produced such films during the war, with the intent of entertaining the troops overseas and civilians back home and to encourage fundraising – as well as to show the studios' patriotism. This film was also the first released by Paramount to be shown for 8 weeks.

Star Spangled Rhythm was directed by George Marshall and others, and written by Harry Tugend with sketches by Melvin Frank, George S. Kaufman and others. The film has music by Robert Emmett Dolan and songs by Harold Arlen and Johnny Mercer, and the cast consisted of most of the stars on the Paramount roster.
