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.[3] He was the youngest son of Taejo of Goryeo and Lady Dongyangwon,[4] and the 15th son of Taejo overall.
