"Mad About You" is a song by American singer Belinda Carlisle. It was written by Paula Jean Brown, James Whelan and Mitchel Young Evans, and produced by Michael Lloyd for Carlisle's debut solo album, Belinda. The song was released in 1986 as Carlisle's debut solo single after leaving the Go-Go's. The song peaked at number three on the U.S. Billboard Hot 100 chart and at number one on Canada's RPM 100 Singles chart. The song was later included in the jukebox musical Head over Heels that used the Go-Go's music in addition to two of Carlisle's solo tracks. The musical debuted on Broadway in 2018.
