Lê Thánh Tông (黎聖宗; 25 August 1442 – 3 March 1497), personal name Lê Hạo, temple name Thánh Tông, courtesy name Tư Thành, was an emperor of Đại Việt, reigning from 1460 to 1497, the fifth and the longest-reigning emperor of the Later Lê dynasty, and is widely praised as one of the greatest emperors in Vietnamese history. He came to power through a coup d'état against his second brother Lê Nghi Dân in 1460.

His reign is recognized for the extensive administrative, military, education, and fiscal reforms he instituted, conquests of Champa states and expansion of Đại Việt territory in the south, and a cultural revolution that replaced the old aristocracy with a generation of literati scholars. His reign was later praised as the Prospered reign of Hồng Đức (Hồng Đức Thịnh trị; 洪德盛治).
