Peggy Mondo was an American actress known for playing roles of overweight characters. Her early background included training as an opera singer before making her Broadway theatre debut in the late 1950s musical The Music Man and later appeared in the 1962 film adaptation. Mondo felt she was typecast into roles that emphasized her weight.

The Music Man is a 1962 American musical film directed and produced by Morton DaCosta, based on Meredith Willson's 1957 Broadway musical of the same name, which DaCosta also directed. Robert Preston reprises the title role from the stage version, starring alongside Shirley Jones, Buddy Hackett, Hermione Gingold, Ronny Howard, and Paul Ford.
