Algrøyna or Algrøy is an island in Øygarden Municipality in Vestland county, Norway. The 4.9km2 island lies just west of the large island of Sotra and north of the small island of Lokøyna. There are a series of bridges connecting it to the island of Sotra, which in turn is connected to the mainland. The highest point on the island is the 78m (256feet) tall mountain Hillefjellet. Almost all the residents of the island live along the northern shore, in a village area that is referred to as Algrøyna.[1]
