, is a province or landskap in the north of Sweden. It borders Ångermanland, Lapland, Norrbotten and the Gulf of Bothnia. It is famous for the cheese with the same name as the province.
Västerbotten was historically divided into chartered cities and districts.
Up until the Finnish War 1808-1809 and the Treaty of Fredrikshamn the province of Västerbotten also included a small part of today's Finland. This part has later been integrated in Lapland, Finland.
Västerbotten County was in 1810 split in two parts. The northern part got the name Norrbotten County. The locals of Norrbotten then started referring to themselves as Norrbothnians. The county borders thus gradually led to a local provincial identity. Nowadays Norrbotten is considered a separate province.
Västerbotten Regiment was the provincial regiment.
