Đặng Dung (Chữ Hán: 鄧容, 1373–1414) was the poet and general of the later Tran Dynasty in Vietnamese history.
During the short-lived Ho dynasty, Đặng Dung assisted his father in governing Thuận Hóa.
In response, Đặng Dung and his father participated in the insurrection led by Trần Ngỗi, also known as Giản Định Đế.
Outraged by these events, Đặng Dung left Trần Ngỗi and, along with Nguyễn Cảnh Di (son of Nguyễn Cảnh Chân), led the troops from Thuận Hóa to Thanh Hóa and successfully depose the emperor.
In 1413, when the Ming forces launched an offensive against Thanh Hóa and Nghệ An, both Giản Định and Trần Quý Khoáng's armies retreated to the mountains and forests.
