I Don't Want to Be Born (U.S.
 The Devil Within Her; also known as The Monster) is a 1975 British horror film, directed by Peter Sasdy and starring Joan Collins, Ralph Bates, Eileen Atkins and Donald Pleasence, which tapped into the 1970s fad for devil-child horror films.

 However it later gained a reputation as a cult film favourite due to its perceived shortcomings, absurdities and unintentional camp comedy appeal.
