Lê Dụ Tông (Hán Nôm : 黎裕宗, 1679 – 27 February 1731), born Lê Duy Đường (黎維禟) was an emperor of Vietnam, the 22nd emperor of the Later Lê dynasty.

Crown Prince Lê Duy Đường reigned as emperor from 1705 to 1729 (24 years), the first ten years of which his father Lê Hy Tông was alive and elevated in semi-retirement to Retired Emperor (Vietnamese: Thái thượng hoàng).

He was succeeded by Lê Duy Phường, also known as the second emperor to carry the title as Hôn Đức Công (means "degraded morality").

[note 1][1] He had five sons.

They are Lê Duy Phường, Lê Duy Mật, Lê Duy Quý, Lê Thuần Tông and Lê Ý Tông.
