"La Grange" is a song by the American rock group ZZ Top, from their 1973 album Tres Hombres. One of ZZ Top's most successful songs, it was released as a single in 1973 and received extensive radio play, rising to No. 41 on the Billboard Hot 100 in June 1974. The song refers to a brothel on the outskirts of La Grange, Texas (later called the "Chicken Ranch"). The brothel is also the subject of the Broadway play and film The Best Little Whorehouse in Texas.

The first time ZZ Top played the song in La Grange, Texas was during the Fayette County Fair on September 5, 2015.

In 2020, the song reentered the Billboard charts following the release of the documentary ZZ Top: That Little Ol' Band from Texas.[
