Clayton Moore 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, then later 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 convinced 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.
