Lý Thánh Tông (Vietnamese pronunciation: [li t?aj?? t?w?m]; born Lý Nh?t Tôn [li ??`t ton], ruled 1054–1072) was the posthumous title of the third emperor of the Lý dynasty of Vietnam.
In his reign, Lý Thánh Tông promoted the agricultural development, reducing some harsh laws and building many Confucianist and Buddhist institutions, most notably the first Temple of Literature in Vietnam (1072).
He also fought several successful wars with the Song empire and Champa, resulting in the expansion of Vietnamese territory to the areas which are Qu?ng Bình Province and Qu?ng Tr? Province today.
