Prince Deokheung (Hangul: 덕흥군, Hanja: 德興君), personal name Wang Hye (Korean: 왕혜; Hanja: 王譓) was the third son of Chungseon of Goryeo who became a Mongolian-backed pretender to the throne of Goryeo. After the ascension of King Gongmin, his half-nephew, to the throne of Goryeo, Prince Deokheung left Goryeo and settled in the Yuan capital of Dadu. Since then, he was also known by his Mongolian name, Tash Temür (塔思帖木兒) which spelled as Tapsacheopmoka (탑사첩목아) in Sino-Korean. At one point in his life, he was a Buddhist monk but he later returned to a secular life.
