Borgøy (alternately spelled Borgøya or Borgøyna) is an island in Tysvær municipality in Rogaland county, Norway. The 4.5km2 island is located at the southern end of the Skjoldafjorden. South of the island lies the Hervikfjorden. The highest point on the island is the 292m (958feet) tall mountain Borgøyhatten.[1]
The island is accessible only by boat as there are no bridge or tunnel connections. The main population centre is the relatively flat southwestern coast of the island. Borgøy was the birthplace of painter Lars Hertervig.[2] The island has tin and granite mines.
