Terror Circus (also released as The Barn of the Naked Dead and Nightmare Circus) is a 1973 American exploitation horror film directed by Alan Rudolph, and starring Andrew Prine, Manuela Thiess, Sherry Alberoni, Gyl Roland, and Sheila Bromley. It follows three showgirls who are kidnapped in the desert by a psychopath who imprisons women in his barn near the former site of a nuclear disaster.

The film's director and writer is credited as Gerald Cormier, the name of a stunt man and head of the film's distributor, CMC Pictures. Some sources indicate that Cormier's name was a pseudonym for Rudolph. According to actor Prine, however, Cormier himself was one of two other directors hired to shoot the film before Rudolph took over directorial duties.
