Brändöskär and Uddskär are two islands in the northwest of the Swedish sector of the Bay of Bothnia, in the Luleå archipelago, joined by an isthmus.

Brändöskär is located in the outer part of the Luleå archipelago, about 20 kilometres (12 mi) east of Lövskär on the mainland.

The cottages and boathouses of a fishing village were built around the bay between Brändöskär and Uddskär when the two islands were separate.

The wall sections and other material were being barged to the harbor, and then lifted to the construction site by helicopter to avoid any damage to the land.

[3] The Brändöskär municipal nature reserve was founded in 2005, covering 212 hectares (520 acres) between the chapel and the southern tip of the island.

At other times, hiking, fishing and hunting are allowed, as are picking berries and mushrooms, camping and making fires on designated sites.

[3] In 1820 about thirty boats were based at Brändöskär / Uddskär, the largest fishing village in the Luleå Archipelago.

The main catch was herring, which was caught in nets, salted and sold in wooden barrels in Luleå, Haparanda, Raahe and Oulu.

Whitefish, grayling, salmon, pike, perch and ide were also caught, but mainly consumed locally.
