"Autumn Leaves" is a much-recorded popular song. Originally it was a 1945 French song "Les feuilles mortes" (literally "The Dead Leaves") with music by Joseph Kosma and lyrics by poet Jacques Prévert. Yves Montand (with Irène Joachim) introduced "Les feuilles mortes" in 1946 in the film Les Portes de la Nuit. The American songwriter Johnny Mercer wrote English lyrics in 1947 and Jo Stafford was among the first to perform this version. Autumn Leaves became a pop standard and a jazz standard in both languages, both as an instrumental and with a singer.

On December 24, 1950, French singer Edith Piaf rendered both French and English versions of this song on the radio program The Big Show, hosted by Tallulah Bankhead.

The film Autumn Leaves(1956) starring Joan Crawford featured the song, as sung by Nat King Cole over the title sequence. The French songwriter Serge Gainsbourg paid tribute to this song in his own song "La chanson de Prévert".

One of the most referred-to instrumental versions of this song is the one on the Cannonball Adderley album called "Somethin' Else" released in 1958, whose personnel included Miles Davis on trumpet, Hank Jones on piano and Art Blakey on drums.

The song also crossed over in the club scene when dance act Coldcut recorded a version in 1994, the resulting remix by Irresistable Force became widely regarded a classic of the chillout genre.

It is the corps song of the Bluecoats Drum and Bugle Corps.

In 2009 Cecile Bredie made a wonderful version, the song can be found in the compilation "Cafè del Mar volume 16".

In 1955 Roger Williams made the song a number one hit in the United States, the only piano instrumental to reach number one and remaining in that position for four weeks.
