Princess Heunggyeong (; d. 1176) was a Goryeo Royal Princess as the youngest daughter of King Yejong and Queen Sundeok, also the youngest sister of King Injong.
It seems that she was born after 1109 not long after her older sister, Princess Seungdeok. She was the paternal aunt of the three rulers: Uijong, Myeongjong and Sinjong. Her maternal grandfather was Yi Cha-gyà Âm from the powerful Gyeongwon Yi clan.
She was firstly called PrincessâÂÂ"gungju" () but later on 9 October 1124 changed into PrincessâÂÂ"gongju" (). Then, she married Wang Kyà Âng, Duke Anpyeong () and died in 1176 (6th year reign of King Myeongjong).
