Sid Jordan (August 12, 1889 – September 30, 1970) was an American film actor.

Born in Muskogee, Oklahoma in 1889, Jordan was introduced to acting through his close friend Tom Mix, when both men were serving as the "Night Marshalls" of Dewey, Oklahoma. Ironically, it was Sid Jordan's father (Col. John Jordan) who helped Sid and Tom Mix obtain their jobs as Night Marshalls, as John Jordan was Sheriff of Washington County, Oklahoma. Sid and Tom made their first film together in Oklahoma, then starred in many films together in Los Angeles, along with Victoria Forde, Tom Mix's wife at that time. Jordan appeared in 130 films between 1913 and 1944. He died in Hemet, California, in 1970.
