Frösön (, ; "Frey's island") is the largest island in the lake Storsjön, Jämtland, Sweden. Part of the city Östersund is located on the island. During most of recorded history Frösön was the regional centre of Jämtland, and it is the location of the Frösö Runestone, the northernmost in the world. The Swedish composer Wilhelm Peterson-Berger had a summer house (and from 1930 a permanent home) on the island. In 1896 Peterson-Berger composed a set of piano pieces entitled Frösöblomster (Flowers of Frösön), and his opera Arnljot from 1910 is partly based on the runic inscriptions on Frösö Runestone.

History

Frösön is named after the Norse god Freyr. It is the location of the "Frösö Runestone", the northernmost raised runestone in the world, dating from 1030-1050 AD. Frösön was a separate köping until 1974 but was merged with Östersund at that time.

Hospital

From 1915 to 1988, Frösön was the location of Frösö sjukhus, a state-owned psychiatric hospital tasked with caring for patients from all of Norrland. The hospital's practices have later been questioned, and it is known to have anonymously buried at least roughly 50 of its patients.
