Red River Delta

The Red River Delta (Vietnamese: Đồng Bằng Sông Hồng) is one of the 8 regions of Vietnam. It is located in the centre of northern Vietnam, and is a grouping of 7 provinces and 2 cities. It borders the North Eastern Region to the north, the North Western Region to the west, and the North Central Region to the south.

It is the most densely populated region in all of Vietnam, and also the most populous, containing 21,965,364 people (around 23% of Vietnam's population), and roughly equivalent to the population of Sri Lanka. It is also the smallest of all the 8 regions.

Its largest city by population is Hanoi, and Hanoi Municipality (Hanoi Metro Area) is the largest and most populated subdivision of the region, with 28% of the population.

The region is mostly flat, fertile delta landscape, made up of extremely rich soil suited for farming such as rice plantations. The region's highest point is Tam Đảo.
