Kheshig were the imperial guard for Mongol royalty in the Mongol Empire, particularly for rulers like Genghis Khan and his wife Börte. Their primary purpose was to act as bodyguards for the emperors and other important nobles. They were divided into two groups: the day guard (Torguud) and the night guard (Khevtuul). They were distinct from the regular army and would not go to battle with them, instead staying back on guard duty. Their supreme commander was called the Cherbi.

An imperial guard or palace guard is a special group of troops of an empire, typically closely associated directly with the emperor or empress. Usually these troops embody a more elite status than other imperial forces, including the regular armed forces, and maintain special rights, privileges and traditions.
