Janet Brown (born December 1923 in Rutherglen, South Lanarkshire) is a Scottish actress, comedienne and impressionist.
She presented Picture Book on BBC Television in the 1950s and was celebrated in the 1980s for her impersonation of Margaret Thatcher on television, in radio show The News Huddlines, on record, and on film in the 1981 James Bond film For Your Eyes Only. She is occasionally confused with fellow actress and comedienne Faith Brown because they have the same surname and are both best remembered for their Margaret Thatcher impersonations.
She was married to the late Carry On actor Peter Butterworth, with whom she had a son, the actor Tyler Butterworth, and a daughter, now deceased. She lives alone in Hove.
