Violet Elizabeth Malone (stage name Molly Malone) (December 7, 1888 – February 14, 1952) was an American actress of the silent film era. She appeared in 86 films between 1916 and 1929. Her father, Lewis Malone, was a metallurgist for mining companies. Her mother was Violet St. John, born in Nebraska to immigrant parents from England.

She started her movie career at the relatively late age of 29 but soon caught the eye of comedic actor and director Roscoe "Fatty" Arbuckle who cast her in a number of his shorts including Back Stage and The Garage plus his feature film The Round-Up. She also appeared in films directed by John Ford and Clarence Badger. Her last film was the Universal-Stern silent comedy short The Newlyweds' Pest in 1929.
