Tr?n D? Tông (Hán t?: ???, 22 November 1336 — 25 May 1369), given name Tr?n H?o (??), was the seventh emperor of the Tr?n dynasty, and reigned over Vietnam from 1341 to 1369.
Enthroned by Senior Emperor Minh Tông after the death of his elder brother Hi?n Tông, D? Tông nominally ruled Ð?i Vi?t under the regency of the Senior Emperor until the latter's death in 1357 and held the absolute position in the royal court for twelve more years.
The reign of D? Tông was seen by historical books as the starting point for the third phase of Tr?n Dynasty when the peaceful and prosperous state of the country began to fade away and the royal family fell into a long period of chaos before ultimately collapsing.
