English: Sterling Walter Hayden (born Sterling Relyea Walter; March 26, 1916 – May 23, 1986) was an American actor and author.

Hayden became a print model and later signed a contract with Paramount Pictures, who dubbed the 6′5″ actor "The Most Beautiful Man in the Movies" and "The Beautiful Blond Viking God." His first film, Virginia (1941), starred Madeleine Carroll, with whom he fell in love and married.

After two film roles, he left Hollywood and joined the United States Marine Corps as a private, under the name John Hamilton, a nom de guerre he never used otherwise. While at Parris Island, he was recommended for Officer Candidate School. After graduation, he was commissioned a second lieutenant and was transferred to service as an undercover agent with William J. "Wild Bill" Donovan's COI office. He remained there after it became the OSS.
