The Goseong Lee clan (Korean: 고성 이씨; Hanja: 固城 李氏) is a Korean clan.
Their bon-gwan is in Goseong County, South Gyeongsang Province.
Their founder was Yi Hwang, who was appointed as Lord of Goseong after he successfully defeated the Khitans.
[1] Yi Hwang lived during the reign of King Deokjong of Goryeo.
He was supposedly the 24th descendant of a certain Li Pan (Chinese: 李槃) from the Han dynasty, who had entered the Korean peninsula during Emperor Wu's conquest of Wiman Joseon.
