Robert House Peters Sr. (12 March 1880 – 7 December 1967) was a British-born American silent film actor, known to filmgoers of the era as "The Star of a Thousand Emotions".

Born in Bristol, Gloucestershire, England, Peters began his career on a high note, playing the handsome leading man in In the Bishop's Carriage (1913), co-starring Mary Pickford.

While The Bishop's Carriage was filmed in an East Coast studio, Peters was in Los Angeles by 1914, becoming one of the first screen stars to permanently settle there.

Although he stated publicly that he preferred playing villains, Peters, curly haired and pleasantly dimpled, was from the outset typecast as the romantic hero.

Retired after 1928's Rose Marie, Peters returned for a guest appearance in The Old West, a 1952 Gene Autry film that also featured his son, House Peters Jr., who subsequently enjoyed a lengthy film career portraying villains as well as Procter and Gamble's Mr. Clean character in cleaning product commercials from the late 1950s into the '60s.
