Dvina Bay in the context of Northwestern Russia

Port of Arkhangelsk (Russian: Архангельский морской торговый порт) is a major seaport at Arkhangelsk, located at the mouth of the Northern Dvina River, 50 kilometres (31 mi) from the Dvina Bay of the White Sea. The important point links with coastal areas of the Russian North. For much of Russia's history this was Russia's main centre of international maritime trade, conducted by the so-called Pomors ("seaside settlers") from Kholmogory.

During the Soviet period it was a major naval and submarine base of the Soviet Navy. It is still a major naval base of the Northern Fleet of the Russian Navy.

The Northern Dvina is a river in northern Russia flowing through Vologda Oblast and Arkhangelsk Oblast into the Dvina Bay of the White Sea. Along with the Pechora River to the east, it drains most of Northwest Russia into the Arctic Ocean. It should not be confused with the Western Dvina (Daugava), to which it is not connected.

The principal tributaries of the Northern Dvina are the Vychegda (right), the Vaga (left), and the Pinega (right).
