Who Will Marry Mary? is a 1913 American action film serial starring Mary Fuller. The film is a sequel to the 1912 serial, What Happened to Mary. While most of the serial is considered to be lost, incomplete prints of episodes one and five survive in the EYE Film Instituut Nederland archive and at Keene Stage College respectively. A digitized print of the first episode "A Proposal From The Duke" was uploaded onto YouTube by the EYE Film Instituut Channel in 2016.
