For the province in Finland, see Lapland (Finland).
Lappland, often anglicised as Lapland (Swedish: Lappland, Northern Sami: Sápmi, Finnish: Lappi, Latin: Lapponia), is a province in northernmost Sweden. It borders Jämtland, Ångermanland, Västerbotten, Norrbotten, Norway and Finland. Nearly a quarter of Sweden's land area is in Lappland.
The traditional provinces of Sweden serve no administrative or political purposes but are cultural and historical entities. Administratively, Lappland constitutes the western part of two counties of Sweden, Norrbotten County in the north and Västerbotten County in the south. In contrast to most other areas of Sweden, there is more of an identification with the counties rather than to provinces. Thus, most people in these counties refer to the entire county, including the areas in Lappland, when they say 'Norrbotten' or 'Västerbotten'.
Citizens of Sami descent are eligible to stand and vote in elections for the Swedish Sami Parliament, which is the case with Sami people elsewhere in Sweden as well. Sami language has an official minority status in Kiruna Municipality, Gällivare Municipality, Jokkmokk Municipality and Arjeplog Municipality.
