Terøya (or Terøy) is a small, populated island in Ålesund Municipality in Møre og Romsdal county, Norway. The population of Terøya (about 200-300 people) is concentrated on the southern and eastern parts of the island. Terøya is connected to the village of Søvik on the mainland by a causeway on the east side. The island of Bjørnøya lies to the west of the island. The two islands are separated by the 300 m wide Bjørnøysundet strait. Terøya is located 3 km from the village of Søvik where the Norwegian shipbuilding company Aker Yards is located (since 2008 that company is a part of STX Norway Offshore AS/STX Europe). Terøya was part of the municipality of Borgund until 1965 and then it was part of Haram Municipality until 2020 when it joined Ålesund.
