Junior Miss is a 1945 American comedy film starring Peggy Ann Garner as a teenager who meddles in people's love lives.

A collection of Sally Benson's stories from The New Yorker was published by Doubleday as Junior Miss in 1941. This was adapted by Jerome Chodorov and Joseph Fields into a successful play that same year. Directed by Moss Hart, Junior Miss ran on Broadway from 1941 to 1943. In 1945, the play was adapted to the film Junior Miss with George Seaton directing Peggy Ann Garner in the lead role of Judy Graves. Junior Miss was adapted as a radio series three times in the late 1940s and early ‘50s, with Shirley Temple and Barbara Whiting performing the lead role.
