Meänmaa, or sometimes Torne Valley or Torne River Valley (Finnish: Tornionlaakso, Swedish: Tornedalen Meänkieli: Meänmaa) lies at the border of Sweden and Finland. It is named after the Torne River flowing through the valley and into the Gulf of Bothnia. Geographically the townships and municipalities that make up the area are Haparanda, Övertorneå, Pajala and Kiruna in Sweden, and Tornio, Ylitornio, Pello, Kolari, Muonio and Enontekiö in Finland. Culturally the Swedish municipality Gällivare is also considered part of Meänmaa due to the large share of Meänkieli-speaking population in it. Torne Valley should not be confused with Torne Valley Sub-region.
The cultural environment around the Torne River is characterized by agriculture, reindeer farming and fishing. Meänmaa was one of the oldest inhabited areas in northern Finland. Archeological excavations have revealed evidence of permanent settlements at least from the 11th century, but there are signs of earlier settlements. Agriculture has long been practiced on the fertile flooding meadows by the river. Trading routes followed the river and some trading centers were formed. One of the centers since 16th century was the island Oravaisensaari at Vojakkala. Today, the main center is the twin city of Haparanda-Tornio.
The Finnish and Swedish sides of the river were once one cultural entity, as before 1809 they were both parts of Sweden. Once the current border between the two countries had been established, each side of the river has become influenced by the majority culture in its respective country, but still retains some traditional elements. As an example, on the Swedish side of Meänmaa one still makes types of food, such as rieska, that are usually considered Finnish rather than Swedish.
