Archipelago National Park (, ) is a national park in Southwest Finland. It was established in 1983 and covers 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.
