Ashley Joanna "Ash" Williams is the anti-hero protagonist of the Evil Dead series, played by Bruce Campbell, and created by director Sam Raimi.

First appearing in the 1981 film The Evil Dead, Ash has become very popular in modern pop culture and one of the few non-monster characters in the "horror" genre to have such notoriety. He is most easily recognized and envisioned in later material based on his final appearance in the second film however, armed with a sawed-off shotgun and a chainsaw strapped to the stump on his right arm where his hand once was.
