Gim Myeong-yun (Korean: 김명윤; Hanja: 金明胤; fl. mid-16th century), also known as Kim Myeong-yun, was a scholar-official of the Joseon period who was involved in the Eulsa purge of 1545. The Eulsa purge took place following the accession of Myeongjong of Joseon, which brought a new in-law family to power.[1] He was serving as the governor of Gyeonggi Province when Yun Won-hyeong began to kill his enemies in the government, including Minister of Punishments Yun Im as well as Minister of Personnel Yu In-suk. Gim told Yun that Prince Gyerim and Prince Bongseong had been aware of the plots of these ministers, and thus brought about the death of Prince Gyerim.
