"Deja Vu" is a song by American rapper J. Cole, released on December 9, 2016 from his fourth studio album, 4 Your Eyez Only. It was released on January 10, 2017, as the first single off the album.

The song was written by Jermaine Cole and produced mainly by Vinylz and Boi-1da, with additional production from Cole, Velous, Ron Gilmore. "Deja Vu" contains samples of "Swing My Way" performed by K. P. & Envyi.

On December 9, 2016, producers Vinylz and Boi-1da accused producer Foreign Teck of stealing their beat, to Cole's track "Deja Vu" and giving it to singer Bryson Tiller for his hit record "Exchange", explaining why the tracks share similarities. Vinylz said Cole's track was recorded before Tiller's, and that he sent Foreign Teck a video of him making the beat to "Deja Vu", and a week later Teck posted a beat on Instagram with the same drums. Vinylz also alleged that Foreign Teck offered him publishing, a tacit admission that he had reverse engineered the beat. In an interview with Billboard, Cole's manager and Dreamville President Ibrahim Hamad revealed that "Deja Vu" was originally intended for Cole's previous album, 2014 Forest Hills Drive.

"Deja Vu" quickly became J. Cole's highest debuting and highest charting song to date. The song charted at number 7 on the Billboard Hot 100 upon the first week of release.
