Yi Chahŭng[2] (born 1305), posthumously known as Grand Prince Wanchang, was a late Goryeo period second rank official (좌윤; 左尹)[3] who became part of the early Joseon royal family member as the first and oldest son of Yi Ch'un, making him uncle to Yi Sŏng-gye, its founder.[4]

He studied under the tutelage of U T'ak as one of his students. Yi served the Yuan dynasty as a chiliarch (천호; 千戶).[5] After his nephew, Yi Sŏng-gye (이성계) established the new dynasty, Yi Chahŭng was posthumously given the office of the minister of military affairs (병조판서; 兵曹判書) and on 9 March 1871, Yi was given the posthumous name Chŏnggan (정간; 貞簡). In 1872, Emperor Gojong of Korea gave him a posthumous name as Grand Prince Wanch'ang (완창대군; 完昌大君) and was enshrined in Yŏngjongjŏnggyŏng (영종정경; 領宗正卿) alongside his parents. Their tomb located at Gwiju-dong, Hamheung.[6]
