Frauengefängnis (lit. Women's prison; released in the US as Barbed Wire Dolls and in the UK as Caged Women) is a 1975 Swiss-West German horror film directed by Jesús Franco. It is part of the women in prison cycle of violent sexploitation films that flourished in the 1970s and early 1980s. A women's prison tale, it stars Lina Romay as Maria, who has been jailed after killing her father, played by director Jesús Franco himself.

When originally submitted for release in 1976, the British Board of Film Classification rejected it. It was only passed the following year after extensive cuts as was the case in Australia.
