Linesøya is an island in the municipality of Åfjord in Trøndelag county, Norway. It lies about off the coast of the mainland of Åfjord, and southwest of the island of Stokkøya.[1] The 16.6km2 island also lies about north of the smaller island of Lauvøya. The highest point on Linesøya is the 230m (760feet) tall mountain Linesfjellet.[2]
After the completion in 2011 of the Linesøy Bridge between Linesøya and Stokkøya and the Stokkøy Bridge from Stokkøya to the mainland, there has been a ferry-free road to the mainland from Linesøya.
