George Nader (October 19, 1921 – February 4, 2002) was an American film and television actor. He appeared in a variety of films from 1950 through 1974, including Phone Call from a Stranger (1952), Congo Crossing (1956), and The Female Animal (1958).
During this period, he also did episodic television and starred in several series, including NBC's The Man and the Challenge (1959–60). He is remembered for his starring role in "one of the worst films ever made", low-budget 3-D sci-fi film Robot Monster (1953).
Discreetly gay during his film career, he and his life partner were among Rock Hudson's closest friends. He later wrote Chrome (1978), a science-fiction novel dealing openly and positively with a same-sex relationship.
