Mary Murphy was an American film and television actress of the 1950s, '60s, and '70s.
She first gained attention in 1953, when she played a good-hearted girl who is intrigued by Marlon Brando in The Wild One. The following year, she appeared opposite Tony Curtis in Beachhead, and with Dale Robertson in Sitting Bull, and the year after that as Fredric March's daughter in the thriller The Desperate Hours, which also starred Humphrey Bogart. She co-starred with actor-director Ray Milland in his Western A Man Alone. That was one of her best roles; another was in the film she made the following year for Joseph Losey, The Intimate Stranger (1956). She was absent from the big screen for seven years before resuming her film career in 1972 with Steve McQueen in Junior Bonner.
