Västerbottens museum, County museum in Umeå, Sweden.

Västerbottens museum is a county museum in Umeå whose main building, designed by Bengt Romare, opened in 1943. Its collections cover archaeology, ethnology, art and documentary photography, and its photo archive holds about eight million images. The adjoining Gammlia open-air museum, with buildings moved from across the county since 1921, includes Helena Elisabeth Church, a manor house, a windmill, a farmhouse, a school, a smithy and three Sami camps.

In January 1886 the Västerbotten County Antiquarian Society resolved to establish a museum in Umeå; its first objects were kept in the Ullbergska property on Storgatan and were destroyed in the city fire of 25 June 1888. The collections moved to the grammar school in 1901 and to a harbour warehouse in 1911. The main building at Gammlia, designed by Bengt Romare, was completed in 1943, and older buildings were moved to the site between 1921 and 1990.

Gammlia takes its name from Gamli, the winning entry in a naming contest held by the local heritage association; it is a dialect form of "the old hillside". Buildings were moved here from across the county between 1921 and 1990, starting with Sävargården from Sävar. In summer, staff guide visitors and demonstrate butter churning, tunnbröd baking and handicrafts, and native Swedish breeds of horses, cows, sheep, pigs and chickens are kept on the grounds.

The museum sits on the Gammlia area, a short walk from central Umeå. The outdoor grounds are open year-round, but the farm buildings can only be viewed from mid-June to late August and during the annual Christmas market. Staff guide visitors and run daily activities in summer.

The museum's logo reproduces a bronze link from a thousand-year-old Sami grave at Vargviken on the Vindel River. The ski collections came to Umeå in 1963, when the holdings of a ski museum opened in 1928 in a ski jump tower at Fiskartorpet, Stockholm, were moved to the Swedish Ski Museum here.
