Torne River

The Torne River, sometimes known as the Tornio, is a river in northern Sweden and Finland (Finnish: Tornionjoki, Swedish: Torne älv, Torneälven, Northern Sami: Duortneseatnu, Meänkieli: Tornionväylä). It defines the boundary between these two nations for almost half of its length.

It begins near the Norwegian border at Lake Torne (Swedish: Torneträsk) and runs southeast for 522 kilometers (324 miles) into the Gulf of Bothnia. By both length and watershed area, it is Norrbotten's longest river. Lake Torne (Swedish: Torneträsk) near the Norwegian border is said to be the source of the Torne. However, Abiskojkka, which flows out of Abiskojaure and is mostly supplied by Kamajkka, which flows from Lake Gamajávri, is the lake's major feeder.

According to official Swedish maps, the Torne River originates from Lake Válfojávri in Norway's Nordland Fylke, however it is joined by an unnamed, longer stream near the lake, which is supplied by a tiny glacier. The river runs south along the Finno-Swedish border from here. Meänmaa is the name given to this area, which is a famous tourist attraction. A border-crossing bridge on a road heading to Kolari, just south of Pajala, is the eighth bridge over the main river from the source. The river continues to Kassa village. This is considered one of the longest rivers in Finland.
