Wang Sŏ, known by his title of Marquess Deokyang and later Duke Yangyang, was a Goryeo Royal Prince as the second son of King Sinjong and Queen Seonjeong, also the only younger brother of King Huijong. Through his third son, he would eventually become an ancestor of King Gongyang. In 1204, his father visited his manor, but died there not long after that. In 1211, he was exiled alongside Huijong by Ch'oe Ch'ung-hŏn to Ganghwa Island.
