H. Bruce 'Lucky' Humberstone (b. November 18, 1901, Buffalo, New York - d. October 11, 1984, Los Angeles, California) was a movie actor (as a child), a script clerk, an assistant director, working with directors such as King Vidor, Edmund Goulding and Allan Dwan and, ultimately, a director.

One of twenty-eight founders of the Directors Guild of America, Humberstone worked on several silent movie films for 20th Century Fox. Humberstone did not specialize; he worked on comedies, dramas, and melodramas. Humberstone is best known today for his work on some of the Charlie Chan films. In the 1950s, Humberstone worked mostly on TV.
