"Déjà Vu" is a hit 1979 ballad written by Isaac Hayes with lyricist Adrienne Anderson, recorded by Dionne Warwick for her album Dionne which Barry Manilow produced.

The song won Warwick a Grammy Award for Best Female R&B Vocal Performance at the 22nd Grammy Awards.

Isaac Hayes had written the tune for "Déjà Vu" in 1977 while touring with Warwick on the A Man and a Woman Tour: Warwick would recall then hearing Hayes play the tune – which he had entitled "Déjà Vu" without writing lyrics – and as she and Barry Manilow began preparing for the January 1979 recording sessions for the Dionne album, Warwick solicited a tape of "Déjà Vu" from Hayes to play for Manilow, who recruited his own regular lyricist Adrienne Anderson to write the words.

[1] Issued in November 1979 as the album's second single – following up Warwick's top ten comeback hit "I'll Never Love This Way Again" – "Déjà Vu" rose to number 15 on the US Billboard Hot 100, number 25 on the Hot R&B/Hip-Hop Songs chart,[2] and number one on the Adult Contemporary chart in early 1980.

The song has also been recorded by Ethel Ennis (album Live at the Maryland Inn/ 1980),[13] Jack Jones (album Don't Stop Now/ 1980),[14] Trudy Kerr (album Déjà Vu: Songs From My Past/ 2008),[15] and by guitarist Peter White (album Playin' Favorites/ 2006) with vocalist Kiki Ebsen.
