William Irving (17 May 1893 – 25 December 1943) was a German-born American film actor.

The burly character actor appeared in more than 220 films between 1916 and 1941, often as a "comic heavy" in the Our Gang and Three Stooges comedy short films. Irving also appeared as a cowardly German army cook in All Quiet on the Western Front (1930). He played mostly supporting roles in the silent era, but after the introduction of sound films his appearances got noticeably smaller and he was often uncredited.

On Christmas Day 1943, Irving was crossing the street at the intersection of Hollywood Boulevard and La Brea Avenue in Los Angeles, California, when he was struck and killed by a hit and run driver. His remains were cremated at Pierce Brothers Hollywood. Irving was divorced from his wife, Mildred, at the time of his death. He was survived by a brother.
