Hà Giang is a province in the Northeast region of Vietnam. It is located in the far north of the country, and contains Vietnam's northernmost point. It shares a 270 km long border with Yunnan province of southern China, and thus is known as Vietnam's final frontier. It covers an area of 7,927.55 km2 (3,060.84 sq mi), comprising 1 city and 10 rural districts, with a population of over 850 thousand people as of 2019.

Đông Bắc is the region to the north of the Red River Delta in Vietnam, bordering China. It is called Northeast to distinguish it from the Tây Bắc or "Northwest", but it is actually in the north and northeast of Hanoi, wider than Việt Bắc or "Northern Vietnam". The Northeast is one of three sub-regions of Northern Vietnam. Sometimes the Northeast includes the Red River Delta.
