"Stir It Up" is a song by American singer Patti LaBelle. It was written by Dan Sembello and Allee Willis and recorded by LaBelle for the motion picture soundtrack album for the 1984 action comedy film Beverly Hills Cop; production was helmed by Harold Faltermeyer and Keith Forsey. "Stir It Up" was the second of two songs she recorded for MCA Records immediately after signing her new contract with them (following "New Attitude"). Her first full-length album for MCA, Winner in You, would follow the next year. Released as the second single from the soundtrack, which was awarded the 1986 Grammy Award for Best Score Soundtrack for Visual Media, it reached number five on the US Hot R&B/Hip-Hop Songs chart. "Stir It Up" was also used as the theme song to the short-lived sitcom Stir Crazy, based on the 1980 movie. The song was later used in South Park: Post Covid at the opening.
