Turn! Turn! Turn! is the second studio album by American rock band the Byrds, released on December 6, 1965, by Columbia Records. Like its predecessor, Mr. Tambourine Man, the album epitomized the folk rock genre and continued the band's successful mix of vocal harmony and jangly twelve-string Rickenbacker guitar. The album's lead single and title track, "Turn! Turn! Turn!", which was adapted by Pete Seeger from text in the Book of Ecclesiastes, had previously been arranged in a chamber-folk style by the Byrd's lead guitarist Jim McGuinn for folk singer Judy Collins' third album, but the arrangement he used for the Byrds' recording of the song utilizes the same folk-rock style as the band's previous hit singles.

The Byrds were an American rock band formed in Los Angeles, California, in 1964. The band underwent multiple lineup changes throughout its existence, with frontman Roger McGuinn remaining the sole consistent member. Although their time as one of the most popular groups in the world only lasted for a short period in the mid-1960s, the Byrds are considered by critics to be among the most influential rock acts of their era. Their signature blend of clear harmony singing and McGuinn's jangly 12-string Rickenbacker guitar was "absorbed into the vocabulary of rock" and has continued to be influential.
