Attack of the Crab Monsters is a 1957 independently made American black-and-white science fiction-horror film, produced and directed by Roger Corman (via his Los Altos Productions), that stars Richard Garland, Pamela Duncan, and Russell Johnson. The film was distributed by Allied Artists as a double feature showing with Corman's Not of This Earth.

The film concerns a second scientific expedition that is sent to a remote Pacific island to discover what happened to the scientists of the first. Unknown to them when they arrive, the island is inhabited by a pair of radiation-mutated giant crabs that not only consumed the members of the first expedition, but absorbed their minds, and now plan to reproduce their kind in numbers.
