Clayton Moore (September 14, 1914 – December 28, 1999) was an American actor best known for playing the fictional western character The Lone Ranger.

Born as Jack Carlton Moore in Chicago, Illinois, Moore was a circus acrobat as a boy. He appeared at the Century of Progress exposition in Chicago in 1934 with a trapeze act. Later Moore enjoyed a successful career as a John Robert Powers model. Moving to Hollywood in the late 1930s, he began working as a stunt man and bit player between modeling jobs. According to his autobiography, around 1940 Hollywood producer Edward Small persuaded him to adopt the stage name "Clayton" Moore. He was an occasional player in B westerns and Republic Studio cliffhangers, ultimately starring in more such films than serial hero Buster Crabbe.

Moore served in the U.S. Army Air Forces during World War II and made training films (Target--Invisible, etc.) with the First Motion Picture Unit.
