The Monolith Monsters is a 1957 American black-and-white science fiction film from Universal-International, produced by Howard Christie, directed by John Sherwood, that stars Grant Williams and Lola Albright. The film is based on a story by Jack Arnold and Robert M. Fresco, with a screenplay by Fresco and Norman Jolley.

The Monolith Monsters tells the story of a large meteorite that crashes in a Southern California desert and explodes into hundreds of black fragments which have strange properties. When those fragments are exposed to water, they grow very large and tall. The fragments also begin to slowly petrify some of the inhabitants of a nearby small town. The story that unfolds becomes one of human survival against an encroaching unnatural disaster, that if not stopped, could become a national ecological nightmare that could pose a possible threat to all of humanity.
