Husarö is an island in the Stockholm archipelago, northeast of Stockholm and south of Norrtälje. There are scheduled ferry services to the island and the journey takes around two and a half hours from the centre of Stockholm.
Husarö housed pilots from the 15th century until 1912 when the piloting station was closed. There is a small pilot museum on the island.
In 1719, during the Great Northern War, the Russians burnt the settlement and much of the forest on the island. The island's shop was burned down in May 2006.
