Peggy Ann Garner (February 3, 1932 – October 16, 1984) was an American actress.

As a child actress, Garner had her first film role in 1938. She won the Academy Juvenile Award for her work in A Tree Grows in Brooklyn (1945). (Whether the award was given specifically for her work in that film is debatable. The Official Academy Awards Database lists the award as "outstanding child actress of 1945," without mentioning a specific film. The Inside Oscar reference book about Academy Awards refers to "Peggy Ann Garner of A Tree Grows in Brooklyn and Junior Miss" in citing the award.)

Featured roles in such films as Black Widow (1954) did not help to establish her in mature film roles, although she progressed to theatrical work and she made acting appearances on television as an adult.
