"Gettin' Jiggy wit It" is a song by American rapper and actor Will Smith, released as the third single from his debut solo album, Big Willie Style (1997). The verse is based around a sample of "He's the Greatest Dancer" by Sister Sledge, and the chorus is sampled from "Sang and Dance" by the Bar-Kays. Released on January 26, 1998, the song was Smith's second hit produced by Poke & Tone and L.E.S., who replaced his long-time partner Jazzy Jeff, though the record-scratching techniques of Jazzy Jeff can be heard in the song.

The song spent three weeks at the top of the Billboard Hot 100 chart from March 14, 1998. It also won a Grammy Award in 1999 for the Best Rap Solo Performance. It was ranked the 68th greatest song of the 1990s by VH1. However, it was ranked at number 19 on the list of AOL Radio's 100 Worst Songs Ever in 2010. The song was included in Pitchfork Media's 2010 list of "The Seven Worst U.S. No. 1 Singles of the 90s".
