Ghoul (Arabic: غول‎, ghūl) is a demon-like being or monstrous humanoid originating in pre-Islamic Arabian religion, associated with graveyards and consuming human flesh. In modern fiction, the term has often been used for a certain kind of undead monster.

By extension, the word ghoul is also used in a derogatory sense to refer to a person who delights in the macabre or whose profession is linked directly to death, such as a gravedigger or graverobber.
