Joan Croydon (May 15, 1908 – April 23, 1985) was an American stage actress.
Born as Vivian Giesen in Tarrytown, New York to a French mother and a father of German/French descent. She was trained as a dancer at Isadora Duncan dance school. She was cast as a substitute lead nun in Max Reinhardt's The Miracle. She also had Broadway credits in the 1930s under her real name.
She appeared in only one film, The Bad Seed, in which she reprised her stage role, Miss Fern. It was rather surprising casting, given that Croydon was a quite lovely young woman at the time, and the character she played, a murderous child’s suspicious teacher, is one described in the play’s stage notes as “dowdy”, “a spinster”, and “middle aged”, and is generally played by much older actresses (i.e. Anne Haney in a television version starring Blair Brown, Richard Kiley and Lynn Redgrave).
Croydon received rave reviews for playing the Mother in William Ball's production of Six Characters in Search of an Author. Croydon then became one of the founding members of The American Conservatory Theater (ACT) which originated in Pittsburgh and is now in San Francisco.
