Charlotte Irene Caffey (born October 21, 1953, Santa Monica, California) is an American rock and roll guitarist and songwriter, best known for her work in the Go-Go's in the 1980s, including writing "We Got the Beat".

Caffey began her musical career as a bass guitar player in the early Los Angeles punk band The Eyes before joining the Go-Go's in 1978 and switching to guitar. She remained friends with fellow band member Belinda Carlisle after the initial break up of the Go-Go's and wrote songs for Carlisle's solo albums.

From 1988 till 1992, she led her own band, The Graces, with Meredith Brooks and Gia Ciambotti, who released an album Perfect View in 1989. Caffey also co-wrote the theme song to the television series Clueless with Anna Waronker, and played piano on the album version of "Foolish Games" by Jewel, as well as co-writing the No. 1 U.S. country hit "But for the Grace of God" with Keith Urban.

Caffey wrote the book, music, and lyrics for Lovelace: A Rock Musical with Anna Waronker. The rock musical debuted at the Hayworth Theatre in Los Angeles in 2008. A new production of Lovelace: A Rock Musical made its United Kingdom debut at the Edinburgh Festival Fringe in August 2010.
