"Déjà Vu" is a hit 1979 ballad song written by Isaac Hayes and Adrienne Anderson and recorded by Dionne Warwick in 1979. It was the second single released from her Arista debut album, Dionne, which was produced by Barry Manilow. The song was Warwick's fifth and last top 40 single of her 1970s period and her second top 40 single following the release of "I'll Never Love This Way Again" in the five years since her number-one single, "Then Came You", featuring The Spinners.

"Déjà Vu" went to number fifteen on the Billboard Hot 100, number twenty-five on the soul chart, and number one on the Adult Contemporary chart in early 1980. Warwick won the Grammy for Best Female R&B Vocal Performance for "Déjà Vu", also winning for Best Pop Female Vocal Performance for "I'll Never Love This Way Again". Warwick became the first artist ever to win the R&B and pop categories on the same night.
