Munjong (29 December 1019 – 2 September 1083), personal name Wang Hwi, was the 11th monarch of the Goryeo dynasty of Korea.
King Munjong was born in 1019 and reigned from 1046 until his death in 1083. During his reign, the central government of Goryeo gained complete authority and power over local lords. Munjong, and later kings, emphasized the importance of civilian leadership over the military. Munjong expanded Korea's borders northward to the Yalu and Tumen Rivers and built many forts to guard the northern border. Additionally, during Munjong's reign many Chinese medicine books entered Goryeo through the Song Dynasty of China.
