Belinda Jo Carlisle ( KAR-lyle; born August 17, 1958) is an American singer and songwriter. She gained fame as the lead vocalist of the Go-Go's, the most successful all-female rock band of all time, and went on to have a prolific career as a solo artist.

Raised in Southern California, Carlisle became the lead vocalist of the Go-Go's after the band's formation in 1978. With their chart-topping debut studio album Beauty and the Beat in 1981, the group helped popularize new wave music in the United States. The Go-Go's were the first (and to date only) all-female band in history who wrote their own songs and played their own instruments to achieve a No. 1 album. The Go-Go's have sold over seven million records worldwide.

After the break-up of the Go-Go's in 1985, Carlisle went on to have a successful solo career with radio hits such as "Mad About You", "I Get Weak", "Circle in the Sand", "Leave a Light On", "Summer Rain", and "Heaven Is a Place on Earth". The Go-Go's reformed in 1999, and Carlisle performed with them until their disbandment in 2022, while also maintaining her solo career.

Carlisle's autobiography, Lips Unsealed, published in June 2010, was a New York Times Best Seller and received favorable reviews. In 1999, Carlisle was ranked No. 76 with the Go-Go's in VH1's 100 Greatest Women of Rock & Roll. In 2011, Carlisle, as a member of the Go-Go's, received a star on the Hollywood Walk of Fame. She and the band were inducted into the Rock and Roll Hall of Fame in 2021, and the California Hall of Fame in 2024.
