Trần Hưng Đạo (Vietnamese: [tʂə̂n hɨŋ ɗâːwˀ]; 1228–1300), also known as Great King of Hưng Đạo, was the Supreme Commander of Đại Việt during the Trần Dynasty.

Born Prince Trần Quốc Tuấn (), he commanded the Đại Việt armies that repelled three major Mongol invasions in the 13th century. His multiple victories over the Yuan Dynasty under Kublai Khan are considered among the greatest military feats in Vietnamese history. The Mongols and Yuan dynasty forces were successful on land, but they struggled heavily with the heat and disease; in addition to these factors, the inexperience at naval warfare in 1287 rendered them incapable of occupying the country for good. General Trần Hưng Đạo’s military prowess has been reflected in many warfare treatises that he authored.

Prince Trần Quốc Tuấn was born right after the Trần Dynasty replaced the Lý Dynasty in 1225 AD, when the last Lý monarch Lý Chiêu Hoàng abdicated the throne in favour of her husband, Trần Thái Tông. Many in the Lý royal family accused the Trần of usurpation, and in particular, the Imperial Regent Trần Thủ Độ, who masterminded the overthrow of the Lý Dynasty.

Trần Quốc Tuấn was born to Prince Trần Liễu, the elder brother of the new child emperor, Trần Thái Tông. That same year, Trần Liễu being the Empress Lý Chiêu Hoàng’s brother-in-law at the time was forced to defer his own wife (Trần Hưng Đạo’s mother) to his younger brother Emperor Thái Tông under pressure from Imperial Regent Trần Thủ Độ to solidify Trần clan’s dynastic stability. The brothers Trần Liễu and Emperor Trần Thái Tông harboured grudges against their uncle Trần Thủ Độ for the forced marital arrangement.
