Marquis Hoài Văn Trần Quốc Toản (, 1267–12??) was a marquis of the Trần Dynasty who was well known for his active role in the second war of resistance of Đại Việt against the Mongol invasion. Although there were only a few historical records about Trần Quốc Toản, he is still widely known as an example of patriotism in Vietnam while he participated and ultimately sacrificed himself for the country at a very young age. Today, story about Trần Quốc Toản is taught in Vietnamese schoolbooks and many places in Vietnam are named in honour of this young hero.
