William Haines, American actor and interior designer (d. 1973)
Charles William Haines (January 2, 1900 – December 26, 1973) was an American actor and interior designer.

Haines was discovered by a talent scout and signed with Goldwyn Pictures in 1922. His career gained momentum when he received favorable reviews for his role in The Midnight Express. He was cast in the 1926 film Brown of Harvard and his performance solidified his screen persona as a wisecracking, arrogant leading man. By the end of the 1920s, Haines had appeared in a string of successful films and was a popular box-office draw.

Haines' acting career was cut short by the studios in the 1930s due to his refusal to deny his homosexuality. He quit acting in 1935 and started a successful interior design business with his life partner Jimmie Shields, and his work was widely patronized by friends in Hollywood. Haines died of lung cancer in December 1973 at the age of 73.
