"Turn! Turn! Turn! (To Everything There Is a Season)" — often abbreviated to "Turn! Turn! Turn!" — 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 Limeliters' 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 covered by the American folk rock band The Byrds, entering at #80 on October 23, 1965, before reaching #1 on the Billboard Hot 100 chart on December 4, 1965, #3 in Canada (Nov. 29, 1965), and also peaking at #26 on the UK Singles Chart. In the U.S., the song holds distinction as the #1 hit with the oldest lyrics.

The lyrics are taken almost verbatim from the book of Ecclesiastes, as found in the King James Version (1611) of the Bible (), though the sequence of the words was rearranged for the song. Ecclesiastes is traditionally ascribed to King Solomon who would have written it in the 10th century BC, but believed by a significant group of biblical scholars to date much later, up to the third century BC. In either case, the lyrics would be the oldest ever in a #1 song.

To every thing there is a season, and a time to every purpose under the heaven:
A time to be born, and a time to die; a time to plant, a time to reap that which is planted;
A time to kill, and a time to heal; a time to break down, and a time to build up;
A time to weep, and a time to laugh; a time to mourn, and a time to dance;
A time to cast away stones, and a time to gather stones together;
A time to embrace, and a time to refrain from embracing;
A time to get, and a time to lose; a time to keep, and a time to cast away;
A time to rend, and a time to sew; a time to keep silence, and a time to speak;
A time to love, and a time to hate; a time of war, and a time of peace.
