Svenska Högarna is a group of islands in the outer archipelago of Stockholm, which has been a nature reserve since 1976. In 2020, the County Administrative Board decided to expand the protected area to include a large sea area around the island group, making it Sweden's largest marine nature reserve.

The sea area is home to a rich marine wildlife and a seabed with healthy ecosystems. There are blue mussels, seaweed and algae belts, among other things. On land, there is a barren archipelago nature with bare rocks. 

There are also several attractions from when the area was a fishing harbour and lighthouse, including a troy castle, a stone labyrinth and a cemetery.

Svenska Högarna is located in Norrtälje municipality, but the nature reserve is managed by the County Administrative Board.
