Famous Monsters of Filmland is an American genre-specific film magazine, started in 1958 by publisher James Warren and editor Forrest J Ackerman.

Famous Monsters of Filmland directly inspired the creation of many other similar publications, including Castle of Frankenstein, Cinefantastique, Fangoria, The Monster Times, and Video Watchdog. In addition, hundreds, if not thousands, of FM-influenced horror, fantasy and science fiction movie-related fanzines have been produced, some of which have continued to publish for decades, such as Midnight Marquee and Little Shoppe of Horrors.
