Roberta Collins (born Roberta Lee Hefley, November 17, 1944 – August 16, 2008) was a film and television actress who was known for her attractive physique, blonde, curly hair, and Marilyn Monroe appearance. She starred in many exploitation films, including the prostitute Clara in Tobe Hooper's Eaten Alive and Matilda the Hun in the science-fiction film Death Race 2000.

Jack Hill, who directed her in The Big Doll House, said of her, "I think she could have had a great career, but she couldn't get her personal life together ... she would be fantastic one day, do everything right, and then she would be out until 4 am partying and the next day she would be useless."
