# List of islands of Bothnian Bay

A list of islands of Bothnian Bay would include 4,001 islands if an island is defined as an area of land more than 20 square metres (220 sq ft) that is surrounded by water.
Bothnian Bay (Swedish: Bottenviken, Finnish: Perämeri) is divided between northern Sweden and Finland. The north of the bay contains a large archipelago area.
