The Elizabeth Arkham Asylum for the Criminally Insane, commonly referred to simply as Arkham Asylum, is a psychiatric hospital in the Batman stories. Many psychopathic criminals, mostly from Batman's own rogues gallery (such as the Joker, Poison Ivy, the Riddler, Two-Face, the Scarecrow, Bane, Killer Croc, and Harley Quinn) have been imprisoned within the Asylum and also escaped from it. The Arkham Asylum is named after the Sanatorium in the fictional city of Arkham, Massachusetts, found in many of H.P. Lovecraft's short horror and science fiction stories, such as "The Colour Out of Space".
