"Hallelujah" is a song written by Canadian singer Leonard Cohen, originally released on his album Various Positions (1984). Achieving little initial success, the song found greater popular acclaim through a recording by John Cale, which inspired a recording by Jeff Buckley.

Following its increased popularity after being featured in the film Shrek (2001), many other arrangements have been performed by many and various singers, both in recordings and in concert, with over 300 versions known. The song has been used in film and television soundtracks and televised talent contests. "Hallelujah" experienced renewed interest following Cohen's death in November 2016 and appeared on multiple international singles charts, including entering the American Billboard Hot 100 for the first time.

"Hallelujah", in its original version, is in 12
8 time, which evokes both early rock and roll and gospel music. Written in the key of C major, the chord progression matches lyrics from the song: "goes like this, the fourth, the fifth, the minor fall, and the major lift": C, F, G, A minor, F.

Cohen wrote around 80 draft verses for "Hallelujah", with one writing session at the Royalton Hotel in New York where he was reduced to sitting on the floor in his underwear, banging his head on the floor. His original version, as recorded on his Various Positions album, contains several biblical references, most notably evoking the stories of Samson and treacherous Delilah from the Book of Judges ("she cut your hair") as well as King David and Bathsheba ("you saw her bathing on the roof, her beauty in the moonlight overthrew you").
