Hwang Yun-gil

Hwang Yun-gil (1536–?), also known as Hwang Yun'gil, was a Korean diplomat and ambassador. He was a member of the Western faction in the Joseon court. He represented Joseon interests in a tongsinsa (diplomatic mission or corresponding envoys) to Sengoku period in Japan when it was controlled by strongman Toyotomi Hideyoshi.

1590 mission to Japan
Between 1590 and 1591, King Seonjo of Joseon sent a mission to Japan led by Hwang Yun-gil, accompanied by Kim Seong-il and Heo Seong. The chronology of this diplomatic embassy encompassed:
 * September 1589 (22nd year of King Seonjo's rule: Gimi year): Dispatch of tongsinsa to Japan decided upon by the Joseon court.
 * March 1590 (23rd year of King Seonjo's rule: Gyeongin year): The tongsinsa were sent to Japan.
 * January 1591 (24th year of King Seonjo's rule: Sinmyo year): Hwang Yun-gil and others returned the port Busan.

A diplomatic mission conventionally consisted of three primary figures—the main envoy, the vice-envoy, and a document official. Also included were one or more official writers or recorders who created a detailed account of the mission. In 1607, Hwang Yun-gil was the main envoy; and he was accompanied by Kim Sŏng-il, who was the vice-ambassador, and Hŏ Son, who was the document official.
