Mosterøy or Mosterøya is an island in Rennesøy municipality in Rogaland county, Norway. The 12-square-kilometre (4.6 sq mi) island lies just southwest of the island of Rennesøy. The smaller islands of Sokn, Bru, and Åmøy lie to the south of Mosterøy and the islands of Klosterøy and Fjøløy lie to the west of Mosterøy. All of these islands are connected together and to the mainland city of Stavanger by a series of undersea tunnels and bridges. The Mastrafjord Tunnel connects Mosterøy to the island of Rennesøy and the Askjesund Bridge connects Mosterøy to the island of Sokn. Both the tunnel and bridge are part of the European route E39 highway.
