Grand Internal Princess Consort Seungpyeong (Korean: 승평부대부인 박씨; Hanja: 昇平府大夫人 朴氏; 10 March 1455 – 20 July 1506), of the Suncheon Park clan, was a Korean Joseon dynasty royal family member though her marriage with Grand Prince Wolsan, the oldest son of Deokjong of Joseon and Queen Sohye.
She was the older sister of Park Won-jong[2] and the maternal aunt of King Jungjong's second wife, Queen Janggyeong.
Since her younger sister died at an early age after giving birth, she had raised her young niece, Yun Myeong-hye, as if she was her daughter.
The Princess consort later became the sister-in-law to Grand Prince Jean, the son of Queen Ansun and King Yejong, when her youngest sister married him.
[8] Another rumor was that Yeonsangun had a long spear placed in the grave of Grand Prince Wolsan and was surprised to see his uncle appearing in his dream while sleeping in the same room with the Princess consort.
[5] Her younger brother had planned to do a rebellion against the king, but during Yeonsangun's 12th year of reign, the Grand Princess died within Gyeongun Palace on 20 July 1506 at the age of 51.
