Tr?n Nhân Tông (7 December 1258–16 December 1308), given name Tr?n Khâm, was the third emperor of the Tr?n dynasty, reigning over Ð?i Vi?t from 1278 to 1293.
After ceding the throne to his son Tr?n Anh Tông, Nhân Tông held the title Retired Emperor (Vietnamese: Thái thu?ng hoàng) from 1294 to his death in 1308.
During the second and third Mongol invasions of Ð?i Vi?t, the Emperor Nhân Tông and his father the Retired Emperor Thánh Tông were credited as the supreme commanders who led the Tr?n dynasty to the final victories and since established a long period of peace and prosperity over the country.
