Lady Daemyeong

Lady Daemyeong of the Cheongju Yu clan (Hangul: 대명궁부인 유씨, Hanja: 大明宮夫人 柳氏) was a Korean Royal Consort to the King Gyeongjong of Goryeo. She had no issue with him. She later posthumously named as Daemyeonggungbuin or Lady Daemyeong (Hangul: 대명궁부인, Hanja: 大明宮夫人).

Yu's husband, Gyeongjong of Goryeo, actually was her foreign cousin and his other wife also her foreign cousin too. Actually, her clan was Kaesong Wang clan (개성 왕씨), but later changed to Cheongju Yu clan (청주 유씨). There was no record in Goryeo-sa about her birth and death day.
