Ashley Cox (born November 15, 1956) is an American nude model and actress. She was Playboy magazine's Playmate of the Month for its December 1977 issue. Her centerfold was photographed by Mario Casilli. Cox was one of Hugh Hefner's "Personal Playmates", a term Hefner designated women that he dated seriously.
She has been acting since before she was a Playmate, appearing in the 1976 sci-fi film Logan's Run. Her career continued following her appearance in Playboy, but she left the business in 1984 and returned to Texas, where she found work as a legal secretary and, for a time, owned an aerobics studio.
Cox appeared in movies such as Logan's Run, Drive-In, and Looker.
She also had two children and, as she told The Playboy Book in 1996:
'I've been married several times, and I'm still looking for my knight in shining armor. Men think they want a fantasy girl, but when they meet somebody who's been a centerfold and dated a couple of well-known actors, I think that overwhelms them.'
