The Ume River (Swedish: Ume älv or Umeälven) is one of the main rivers in northern Sweden. It is around 460 km (290 mi) long, and flows in a south-eastern direction from its source, the lake Överuman by the Norwegian border within the Scandinavian mountain range. For large parts, the European route E12, also known as Blå Vägen (Blue Route), follows its path.
The river passes through Vindelfjällen Nature Reserve and Lake Storuman and drains into the Gulf of Bothnia. Its chief tributary is the Vindel River, which is the biggest tributary river in Sweden. The Ume and Vindel rivers meet at the village of Vännas.
