A mask that through magical or mundane means, kills the person wearing it. The mask does this by smothering, strangling, suffocating, crushing, or poisoning its victim.

Subtrope of ArtifactOfDeath and possible ArtifactOfDoom. Related to EvilMask. Contrast with FaceHugger which, unlike the Murderous Mask, is often sentient and able to apply to the unwilling victim's face all by itself.

[[folder: Literature ]]

* In Creator/DianeDuane's Literature/{{Rihannsu}} ''Franchise/StarTrek'' novels, Romulan starships are frequently named ''Rhea's Helm''.

When the helm was donned, the demon she'd bound into it ''bit the wearer's head off''--nothing can harm a dead person.
* The Creator/GrahamMasterton horror novel ''Literature/DeathTrance'' features a scene where one of the bad guys, a psychotic Vietnam vet, puts on a full-head demon-mask featuring a leyak, an Indonesian evil spirit. He writhes in agony, to the accompaniment of screams and crunching noises, as his buddies try to get the mask off, but when it finally comes free, the dead man has no head left. Something has eaten his head while he was wearing the mask...
* Somewhat related is [[NewJediOrder Yuuzhan Vong]] vonduun crab armor. If worn by a non-Yuuzhan Vong, it will repeatedly attempt to kill its wearer.
** A notable example of the Vong armor is the one that the Sith lord Darth Krayt wears in the Legacy comic book series. The fact that it is eating Krayt alive is the source of much angst on his part and his frantic attempts to find a cure.
