The Gulf of Bothnia (/ˈbɒθniə/; Finnish: Pohjanlahti; Swedish: Bottniska viken) is divided into the Bothnian Bay and Bothnian Sea, and it is the northernmost arm of the Baltic Sea, between Finland's west coast (East Bothnia) and the northern part of Sweden's east coast (West Bothnia and North Bothnia). In the south of the gulf lies Åland, between the Sea of Åland and the Archipelago Sea.
