Princess Ch'ŏngyŏn (청연공주; 14 July 1754 – 7 July 1821[1]) was a royal princess of the Joseon Dynasty. She was the eldest daughter of Crown Prince Sado and Lady Hyegyeong.
Princess Ch'ŏngyŏn was born in the 30th year of Yeongjo’s reign as the eldest daughter of Crown Prince Sado and Crown Princess Consort Hye[2] She had two older brothers, Crown Prince Uiso and Jeongjo of Joseon, and one younger sister, Princess Cheongseon. But her eldest brother later died in infancy.
Because Princess Ch'ŏngyŏn was the daughter of the Crown Prince, she held the title of Commandery Princess (군주), a senior 2 rank and thus known throughout her life as Princess Ch'ŏngyŏn (청연군주, 淸衍郡主).
In 1765, the 41st reign of King Yeongjo, she married Kim Du‐Seong (김두성) of the Gwangsan Kim clan, son of Kim Sang-ik (김상익). Kim Du-Seong changed his name to Kim Gi-Seong (김기성).[3]
She died on July 7 in 1821. She was honoured by Emperor Gojong as Princess Ch'ŏngyŏn (청연공주) and her husband was posthumously awarded the title of Prince Consort Gwangeun (광은위).[4]
