Hamnøya[1] is an island in Vevelstad Municipality in Nordland county, Norway. The 16.6km2 island lies about 500to off shore from the mainland of the municipality, separated by the Vevelstadsundet strait. The island is only accessible by boat and in 2021 it had 35 permanent residents living on the island.[2]
The southern part of the island is rocky, but relatively low. The northern part has a well-developed beach area. There is a county road that crosses the island from the south (Hamnsundet) to the north (Vågsodden) with a car ferry from Vågsodden to Forvik on the mainland and also to Tjøtta in Alstahaug Municipality.
In the middle of the island at Hesstun, remains of settlements inhabited from the Stone Age to the Early Iron Age have been found.
