Paul Shenar (born February 12, 1936 in Milwaukee, Wisconsin, United States; died from AIDS October 11, 1989 in West Hollywood, California, United States) was an American actor of Turkish and Jewish ancestry.

Shenar gained attention playing larger-than-life entertainment legends on '70s TV. He portrayed Orson Welles in the TV movie The Night That Panicked America (1975) (TV) and Florenz Ziegfeld Jr. in Ziegfeld: The Man and His Women (1978) (TV). He is probably most-known for playing the murderous drug lord Alejandro Sosa in Brian DePalma's 1983 version of Scarface.

A founding member, actor, director, and teacher of the American Conservatory Theatre (ACT) in San Francisco, he played more than 40 roles there, including "Hamlet," "Oedipus Rex" and "Tiny Alice."

Known for his unsympathetic portrayals, he voiced the evil rat Jenner in the animated feature The Secret of NIMH (1982).
