Halsnøya or Halsnøy is an island in Kvinnherad municipality in Vestland county, Norway.
Prior to 2008, it was the most populated island in Norway without a direct connection to land, but the Halsnøy Tunnel opened that year, finally connecting it to the mainland by road.
[2] The island was the site of the Halsnøy Abbey (closed in 1536), which once was one of the richest monasteries in Norway.
In 1896, one of the oldest boats recovered in Norway was found in the Toftevåg bay on the north side of the island.
Some of its most popular tourism attractions include Radiohola, the Halsnøy Abbey, and the Høylandsbygd shipping mural.
