List of islands in the Baltic Sea

This is a list of islands in the Baltic Sea. The Baltic Sea proper is bordered to the north by the Bothnian Sea and, further north, the Gulf of Bothnia, neither being part of the Baltic Sea proper. The eastern basins the Gulf of Finland and the Gulf of Riga are likewise not considered part of the Baltic Sea proper. Whether islands situated in, or on the borders to, these basins shall be included in the list is therefore a matter of definition.
