Sarah Jane Morris (born 21 March 1959) is an English singer of pop, jazz, rock and R&B and a songwriter. In 1982, Morris joined The Republic as lead singer.

A London-based Afro-Caribbean-Latin band, they received enormous publicity from the music press including cover stories with NME and City Limits and a documentary for Granada TV. But the band was deemed too political for radio play, with the exception of Capital Radio. The Republic were signed to Charlie Gillett's Oval Records Ltd and released an EP entitled Three Songs From The Republic and two singles entitled "One Chance" and "My Spies".
