"Everybody Have Fun Tonight" is a song by the English new wave band Wang Chung, released as a single from their fourth studio album Mosaic in 1986. Collaboratively written by Jack Hues, Nick Feldman, and Peter Wolf, it reached no. 2 on the US Billboard Hot 100 chart during the 1986 Christmas season. It also hit No. 1 on the Canada RPM Top 100 Singles chart the week of 17 January 1987. With some different lyrics, the original ballad version of the song was placed on the B-side.

In 2005, Wang Chung performed the song on the American television show Hit Me, Baby, One More Time alongside a cover of Nelly's "Hot in Herre". The song was later featured in the second trailer for the upcoming 2026 video game, Grand Theft Auto VI.

Billboard called it a "self-celebrating dance rocker" that "[coins] a new verb."
