Coleen Gray was an American actress. She was best known for her roles in the films Nightmare Alley (1947), Red River (1948), and Stanley Kubrick's The Killing (1956).

Nightmare Alley is a 1947 American film noir directed by Edmund Goulding from a screenplay by Jules Furthman. Based on William Lindsay Gresham's 1946 novel of the same name, it stars Tyrone Power, with Joan Blondell, Coleen Gray, and Helen Walker in supporting roles. Power, wishing to expand beyond the romantic and swashbuckler roles that brought him to fame, requested 20th Century Fox's studio chief Darryl F. Zanuck to buy the rights to the novel so he could star as the unsavory lead "The Great Stanton", a scheming carnival barker.
