"Work It" is a single by rapper Nelly which features pop singer Justin Timberlake, released in 2003, from Nelly's 2002 album Nellyville. It peaked at number sixty eight on the Billboard Hot 100, and number seven in the United Kingdom. The song was later used in a Scott Storch remix and included on Nelly's 2003 remix album Da Derrty Versions: The Reinvention.

Jason Nevins had official "Work It" remixes released but another remix by Jason Nevins sampled AC/DC's 1980 song "Back in Black", and received considerable airplay, but was not officially released. The Jason Nevins "Nevins Universal Dub" remix is the music being played in the viral internet sensation clip of Robin Schreiber dancing at the Golden State Warriors basketball game on Nov. 9, 2016

Entertainment Weekly panned the collaboration, stating: "[Nelly] enlists the aid of NSYNC pretty boy Justin Timberlake on "Work It", actually one of the weaker tracks here."NME did the same: "Sadly, [Nelly] might need a history lesson, especially in light of "Work It"'s silly pop-directed collaboration with Justin Timberlake of *N Sync."PopMatters noted that Justin croons in this song.

The video for the song shows Justin and Nelly visiting the Playboy Mansion where they play tennis and meet many of the Playboy Playmates. The video is almost similar to the video of the song "Playmate of The Year", released by Zebrahead, where they also visit the Playboy Mansion, and Hugh Hefner also makes an appearance.
