Carol Leader (born 10 November 1950 in Colchester, Essex) is an English theatrical and television actress. She played Sadie Tomkins in Casualty from 1988 to 1989, Barbara Charlton in Young at Heart from 1980 to 1981 and has also been in Flambards, First and Last, Safe, Peak Practice and 1992 TV series Kevin and Co.
