Mirriam Johnson (born May 25, 1943), known professionally as Jessi Colter, is an American country singer who is best known for her collaborations with her second husband, country musician Waylon Jennings, and for her 1975 crossover hit "I'm Not Lisa".

Colter was one of the few female artists to emerge from the mid-1970s "outlaw country" movement. After meeting Jennings, Colter pursued a career in country music, releasing her first studio LP in 1970, A Country Star Is Born. Five years later, Colter signed with Capitol Records and released "I'm Not Lisa", which topped the country charts and reached the top five on the pop charts. In 1976 she was featured on the collaboration LP Wanted: The Outlaws, which became an RIAA-certified Platinum album.
