The House of Wang was the royal ruling house of the Goryeo dynasty of Korea, from 918 to 1392.
Its founder was Wang Kŏn, the chancellor of Taebong who overthrew its tyrant king Kung Ye and founded the new dynasty of Goryeo. His descendants ruled as kings for 474 years. From 1170 to 1270, the Goryeo kings were puppets of the Goryeo military regime. In 1270, the royal house broke free from the military regime's grasp and volunteered to become vassals of the Mongol Empire. During the Mongol domination of Goryeo, the House of Wang became semi-autonomous vassals of the Yuan dynasty, and engaged in intermarriage with the ruling Borjigin clan. In 1356, King Gongmin was able to restore the independence of Goryeo. However, after the Wihwado Retreat in 1388, Goryeo general Yi Sŏng-gye was able to seize power. In 1392, Yi ended the rule of the House of Wang, proclaiming himself King of Joseon.
