Shao Kahn's Helmet or Shao Kahn's Mask, sometimes referred to as the Mask of Shao Kahn, is an ancient spiked, samurai helmet guise carved out of bone and worn by the vicious warlord Shao Kahn the Konqueror. It is both a feature on his own palace fortress and the symbol of his own ruthless empire in the realm of Outworld. Shao Kahn's own "crown", which conceals his face, first appeared in Mortal Kombat II along with him, though it has taken a more or less different shape and form throughout the Mortal Kombat series. It also became another collectible Relic within the Konquest mode of Mortal Kombat: Armageddon.
In the television series Mortal Kombat: Conquest, Shao Kahn's prized helmet was only worn in the early parts of the first episode. After this, he wears what appears to be the facial portion of a human skull lashed over his face. This is known as Shao Kahn's Facemask.
After Shao Kahn's defeat at the end of Mortal Kombat (2011), his charred and broken helmet is picked up by Quan Chi. In Mortal Kombat X, the helmet, armor as well as his Wraith Hammer were taken as trophies and placed in Quan Chi's Fortress. 
- Shao Kahn's helmet is styled after a Japanese samurai's helm. This style of helm is called a Kabuto.
