Johnny Doughboy is a 1942 American black-and-white musical comedy film directed by John H. Auer for Republic Pictures. It stars Jane Withers in a dual role as a 16-year-old actress who is sick of playing juvenile roles, and her lookalike fan who is persuaded by a group of "has-been" child stars to perform with them in a U.S. troop show. The film features cameos by ex-child stars Bobby Breen, Carl "Alfalfa" Switzer, George "Spanky" McFarland, Baby Sandy, and others. It received an Academy Award nomination for Best Musical Score.

John H. Auer was a Hungarian-born child actor who, on coming to the Americas in 1928, became a movie director and producer, initially in Mexico but, from the early 1930s, in Hollywood.
