Archipelago National Park is a national park in Southwest Finland. It was established in 1983 and covers 500 square kilometres of land areas, a huge land area considering that the area mostly is outer archipelago with few islands even 1 km2 - and the big ones are inhabited and mostly privately owned and thus not part of the national park. The park's web pages give that number as non-qualified "area". It is part of the UNESCO biosphere reserves and received a PAN Parks certificate in 2007.
The park encompasses all state-owned land and water areas owned by the state within the borders of the cooperation area surrounding the park, which is more or less the entire outer archipelago of the Archipelago Sea on the eastern side of the Åland Islands and south of the Korpo, Nagu, Pargas and Kimitoön main islands. The Archipelago Sea Biosphere reserve consists of the national park's cooperation area and the rest of the islands in the Åboland archipelago only accessible by boat or ferry.
