Vargön is an island in the northwest of the Swedish sector of the Bay of Bothnia, in the Piteå archipelago.

[3] The island is mainly covered with coniferous forests, but has open sandy areas.

Raptors that have been seen nesting on the island included osprey, goshawk and hawk.

[1] The island has been considered as a site for wind power generation, as have Rånön in Kalix, Baggen in Piteå and Stor-Brändön in Luleå.

However a 2009 report concluded that construction could not be justified given the relatively small potential capacity, the cost and environmental damage.
