Sŏng Hon (Korean:성혼;Hanja:成渾; 25 June 1535 – 6 June 1598) was a Korean philosopher, poet, and politician during the Joseon period. He was a Neo-Confucianist scholar who was a close friend of the scholar Yi I (Yulgok) and an older contemporary of Yi Hwang (T'oegye), leader of the country's "western faction" (sŏin 서인, 西人) of the period.
Sŏng Hon is often referred to by his stylized name of Ugye ("bull valley") and Mugam ("black stone"). He gained eminence not only as a scholar but as a revered politician and reformer, attaining the position of Fourth State Councillor/Vice Prime Minister (Chwach'ansŏng 左贊成) in the State Council of Joseon (Ŭijŏngbu). Sŏng Hon came from the Changnyeong Sŏng clan (창녕 성씨;昌寧 成氏).
He was the great-grandfather of Yun Jeung through the marriage of his daughter, Lady Sŏng. She married Yun Hwang and produced a son, Yun Sŏn'gŏ, who eventually became the parents of Yun Jeung.
