John Arthur Doucette (January 21, 1921 – August 16, 1994) was an American character actor who performed in more than 280 film and television productions between 1941 and 1987. A man of stocky build who possessed a deep, rich voice, he proved equally adept at portraying characters in Shakespearean plays, Westerns, and modern crime dramas. He is perhaps best remembered, however, for his villainous roles as a movie and television "tough guy".
