Haparanda (Finnish: Haaparanta, meaning aspen + river bank) is a locality and the seat of Haparanda Municipality in Norrbotten County, Sweden. It is adjacent to Tornio, Finland. Haparanda had a population of 4,856 in 2010, of out of a municipal total of 10,200 inhabitants.
Haparanda is, despite its small population, for historical reasons often still referred to as a city. Statistics Sweden, however, only counts localities with more than 10,000 inhabitants as cities. The municipality itself, on the other hand, uses the term Haparanda stad (City of Haparanda) not only for the town itself, but for its whole territory (927 km2). At 24° 8' E, Haparanda is Sweden's easternmost settlement.
When Sweden ceded Finland to Russia in 1809, the border was drawn along the Rivers Tornio and Muonio. The town of Tornio, located on the island Suensaari in the river delta became part of the Grand Duchy of Finland within the Russian Empire as demanded by czar Alexander I. (Finland declared independence in 1917).
