Joan Lorring, born Mary Madeline Ellis is a Hong Kong-born American actress and singer known for her work in film and theatre. Soon after, her family moved to Los Angeles, Madeleine (known by her nickname "Dellie") began working as a child actress in radio and film – she was credited as "Dellie Ellis" when she played the title role in the radio program A Date With Judy (1942). She eventually adopted Joan Lorring as her stage name.

Lorring made her Broadway debut in 1950, originating the role of Marie Buckholder opposite Shirley Booth in Come Back Little Sheba. Terry Moore later played Marie in the 1952 film version. For this role, Lorring won a Donaldson Award for Most Outstanding Female Debut in the 1949-1950 Broadway season. This success led to her performing in the 1951 Broadway production of the Lillian Hellman play The Autumn Garden. In 1954, she performed in the play Dead Pidgeons, and her last Broadway appearance was in 1957, originating the role of The Young Woman, opposite Kim Stanley as The Woman, in A Clearing in the Woods by Arthur Laurents.
