The Pite River (Bidumedno in Pite Sami. Piteälven, Pite älv or Piteå älv in Swedish.) is a river in northern Sweden, flowing through the Norrbotten County. It is one of the four major rivers in Norrland that have been left mostly untouched by water power plants, the river has a single dam at Sikfors approximately 15 km upstream from the sea. It starts in the large lakes in eastern Sweden, such as Tjeggelvas, Vuolvojaure and Labbas, in Jokkmokk Municipality, and flows to the east coast, discharging in the Gulf of Bothnia, in the Piteå Municipality.
