"I've Heard That Song Before" is a 1942 American popular song with music by Jule Styne and lyrics by Sammy Cahn. Published by Edwin H. Morris & Co. on September 14, 1942, it became a swing standard. Martha O'Driscoll introduced it in the Republic Pictures film Youth on Parade, with her vocals dubbed by Margaret Whiting. The song was nominated for the Academy Award for Best Original Song for 1942, losing to "White Christmas".
The original recording is by Harry James and His Orchestra, with a vocal by Helen Forrest, made on July 31, 1942. Issued on Columbia 36668 in December 1942 with "Moonlight Becomes You" on the B-side, it reached number one on the US pop charts and the Harlem Hit Parade in early 1943. The recording is heard in Woody Allen's 1986 film Hannah and Her Sisters. Later versions include those by Bing Crosby, Frank Sinatra, Sammy Davis Jr., Pat Boone, Paul Anka, Michael Feinstein and Andrea Marcovicci, and instrumental readings by Al Hirt, who recorded it as "They're Playing Our Song", and Urbie Green.
