"Turn! Turn! Turn!", sometimes known as "Turn! Turn! Turn! (To Everything There Is a Season)", is a song written by Pete Seeger in the late 1950s.

The lyrics, except for the title, which is repeated throughout the song, and the final two lines, are adapted word-for-word from the English version of the first eight verses of the third chapter of the biblical Book of Ecclesiastes. The song was originally released in 1962 as "To Everything There Is a Season" on the folk group the Limeliters' RCA album 'Folk Matinee' and then some months later on Seeger's own 'The Bitter and the Sweet'.

The song became an international hit in late 1965 when it was adapted by the American folk-rock group the Byrds. The single entered the record chart at number 80 on October 23, 1965, before reaching number one on the Billboard Hot 100 chart on December 4, 1965. In Canada, it reached number three on Nov. 29, 1965, and also peaking at number 26 on the UK Singles Chart.

Pete Seeger (May 3, 1919 – January 27, 2014) was an American folk singer and social activist. A fixture on nationwide radio in the 1940s, he also had a string of hit records during the early 1950s as a member of the Weavers, most notably their recording of Lead Belly's "Goodnight, Irene", which topped the charts for 13 weeks in 1950. Members of the Weavers were blacklisted during the McCarthy Era. In the 1960s, Seeger re-emerged on the public scene as a prominent singer of protest music in support of international causes.
