William Gillespie (24 January 1894 – 23 June 1938) was a Scottish actor.
Gillespie started in Hollywood films from the silent era. He played in about 180 films between 1915 and 1939, although his appearances were often uncredited. Gillespie frequently appeared in Hal Roach comedies from 1917, usually as stuffy official or manager. He supported such "slapstick comedians" as Charlie Chaplin, Charley Chase, Our Gang, and Laurel and Hardy, but was most prolific supporting Harold Lloyd in 60 films.
