The Slim Princess is a 1915 American silent comedy film directed by E. H. Calvert and starring Francis X. Bushman, Ruth Stonehouse and Wallace Beery. The movie was written by Edward T. Lowe, Jr. from a story by George Ade and play by Henry Blossom, and was subsequently remade into a 1920 film starring Mabel Normand. The farcical plot involves a princess of a fictional country, loosely based upon Turkey, in which obese women are prized and the normal-sized protagonist is widely regarded as being too slender.
