Prince Hyoeun (Korean: 효은태자; Hanja: 孝隱太子), personal name Wang Wŏn (왕원; 王垣) or Wang Suk (왕숙; 王肅), also known by his title Prince Dongyang (동양군; 東陽君) and Grand Prince Dongyang (동양대군; 東陽大君) was a prince of Goryeo. He was the youngest son of Taejo of Goryeo and Lady Dongyangwon, and the 15th son of Taejo overall. Through his descendant, Wang Mi (왕미; 王亹, 1365 – ?), ninety percent of the modern day Kaesong Wang clan trace their lineage to Prince Hyoeun. He was the first grandson of Yu Tal (유달) who served as the Minister of Works (공부상서).
