Seong 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 (Toegye), leader of the country's "western faction" (seoin 서인, 西人) of the period.
Seong 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 (Jwachanseong 左贊成) in the Joseon State Council (uijeongbu). Seong Hon came from the Changnyeong Seong clan (창녕 성씨; 昌寧 成氏).
