A vampire hunter or vampire slayer is a fictional occupation in folklore and fiction which specializes in finding vampires, and sometimes other supernatural creatures. A vampire hunter is usually described as having extensive knowledge of vampires and other monstrous or undead creatures, including their powers and weaknesses, and uses this knowledge to effectively combat them.
Vampire hunters range in characterization in fiction from sages with more than average knowledge about the occult, to athletes with the skill and ability to confront vampires with traditional or holy weapons often including wooden stakes and holy water, to supernatural beings themselves who fight vampires with mystical powers. Many characterizations draw from the history and folklore of the Balkans.
A well-known and influential archetypal vampire hunter is Professor Abraham Van Helsing, a character in Bram Stoker's 1897 horror novel Dracula, a foundational work in the genre.
