Melville Ruick (July 8, 1898 – December 24, 1972) was an American actor. During the Great Depression, Ruick doubled as a bandleader and as an actor in theatrical stock. An offer came from CBS to work as a local radio announcer while Ruick was leading a dance band in Los Angeles. He later won an audition for the spot of announcer on the CBS radio show Lux Radio Theater, staying with the show for six years.

He was married to actresses Lurene Tuttle and Claire Niesen (the former of whom he had a daughter with, actress Barbara Ruick). He was also the father-in-law of composer-conductor John Williams and the maternal grandfather of Joseph Williams.
