Chungmok (15 May 1337 – 25 December 1348, r. 1344–1348), born Wang Hŭn (Korean: 왕흔; Hanja: 王昕), was the 29th king of the Goryeo Dynasty of Korea.
He was the eldest son of King Chunghye, and his mother was Princess Deoknyeong.
Chungmok is known in some records by his Mongolian name, Batma Dorji,[1] which is rendered in hanja as Palsamataaji (팔사마타아지; 八思麻朶兒只).
He was asked whether he would prefer to follow the ways of his mother or his father; when King Chungmok answered that he would prefer to follow his mother, the Emperor said that this was a child who knew the difference between right and wrong, and made him king.
During Chungmok's reign, the Goryeo government undertook several reforms to reverse the damage done by his predecessor, and abolished various government agencies that had harmed the people.
