List of R-rated films based on comics

This is a list of films based on comics (including comic books, comic strips, mangas, and graphic novels) that have been or will be rated R by the MPAA. Many of the following films are also based on adult comics. Several films on this list were originally released in theaters with NC-17 or X ratings, but were edited down for television or re-released in theaters with an R rating. Others were released to theaters with a gentler rating such as PG-13, but had R-rated versions for home video. Animated and direct-to-dvd comic book movies with a R rating are accepted on this list. R-rated films like The Toxic Avenger, RoboCop, Darkman, Defendor, and Super will not be added to this list because they are original ideas and not directly based on any particular comic book.
