Queen Yun, Korean Queen (d. 1482)
Deposed Queen Yun of the Haman Yun clan (15 July 1455 – 29 August 1482) was the second wife of Yi Hyeol, King Seongjong and the mother of Yi Yung, Prince Yeonsan. She was Queen of Joseon from 1476 until her deposition in 1479. She was an 11th generation descendant of General Yun Gwan (윤관).

Originally a concubine of the King, she was elevated to queen rank after Han Song-yi's death. The ousting of the Queen in 1479, and her subsequent death by poison in 1482 became a source of recurrent political turmoil, culminating with the First literati purge organized in 1498 by Yeonsan in the 4th year of his reign.
