Robert McKim (August 26, 1886 – June 4, 1927) was an American actor of the silent film era. He appeared in 99 films between 1915 and 1927. He is best remembered for playing the arch villain opposite Douglas Fairbanks's Zorro in The Mark of Zorro in 1920.
McKim starred with Lon Chaney in the 1923 silent version of All The Brothers Were Valiant. One of his last roles was again as a villain in the unfinished silent The Mysterious Island, starring Lionel Barrymore based on the Jules Verne novel. Though McKim shot its silent sequences in 1927, the film was not released until 1929 and McKim was uncredited. He died in Hollywood, California from a cerebral hemorrhage in 1927 at age 40.
