Warren Publishing was an American magazine company founded by James Warren, who published his first magazines in 1957 and continued in the business for decades. Magazines published by Warren include After Hours, Creepy, Eerie, Famous Monsters of Filmland, Help!, and Vampirella.

Creepy was an American horror comics magazine launched by Warren Publishing in 1964. Like Mad, it was a black-and-white newsstand publication in a magazine format and did not carry the seal of the Comics Code Authority. An anthology magazine, it initially was published quarterly but later went bimonthly. Each issue's stories were introduced by the host character, Uncle Creepy. Its sister publications were Eerie and Vampirella.
