"Word Up!" is a funk and R&B song originally recorded by American funk band Cameo in 1986. It was released as the first single from their twelfth album, Word Up! (1986).
The song was written by band members Larry Blackmon and Tomi Jenkins. Its frequent airing on American dance, R&B, and contemporary hit radio, as well as its MTV music video (in which LeVar Burton appears as a police detective trying to arrest the band), helped the single become the band's best known hit.
