"Rock Your Body" is a song by American singer-songwriter Justin Timberlake from his debut studio album, Justified (2002). The Neptunes (consisting of Chad Hugo and Pharrell Williams) wrote and produced the song. The song features background vocals by American singer Vanessa Marquez, who was signed to The Neptunes' Star Trak record label at the time. Jive Records released the track on March 17, 2003, as the third single from Justified. Originally intended to be featured on Michael Jackson's tenth studio album Invincible (2001), Jackson rejected the song along with several other tracks, which were instead given to Timberlake for his debut album. It is an uptempo, disco groove, soul infused song containing influences from Jackson and Stevie Wonder.
