The Old Norse form of the name was just Hinn (-øya meaning 'the island' was added later). The large island is almost divided in two parts by the Gullesfjorden and Kanstadfjorden, and the old name is probably derived from an old verb with the meaning "cleave", "split", or "cut".
Hinnøya is dissected by several fjords, and two very long ones, Gullesfjorden in the Northeast and Øksfjorden in the Southwest, almost sever the island; it is only 5 km (3 mi) between their respective heads. The island contains a mostly rugged and mountainous terrain, especially the southern part. The best agricultural area is in the northeast, in Harstad and Kvæfjord. The southern part is the location of Møysalen National Park, which includes the highest mountain on the island, the 1,262-metre (4,140 ft) tall Møysalen. In the northwestern part of the island, near Forfjord, is a nature reserve containing a valley with forests and bogs, including the oldest pine trees in Norway, more than 700 years old.
Hinnøya is connected to the mainland by the Tjeldsund Bridge across the Tjeldsundet strait. To the west, it is connected to the island of Langøya by the Sortland Bridge, and to the northwest to the island of Andøya by the Andøy Bridge. The Lofoten mainland connection was opened on 1 December 2007. It is part of the European Route E10 highway, and it connects Hinnøya to the Lofoten islands to the southwest. The highway runs near Møysalen National Park. There is also a ferry connection in the southeast between Lødingen and Bognes on the mainland, across the Vestfjorden.
As of 2001[update], Hinnøya had a population of 32,101; the only town is Harstad. Villages include Borkenes, Lødingen, Sigerfjord and Sørvik. The island is split between the municipalities of Harstad and Kvæfjord in Troms county, as well as Andøy, Hadsel, Lødingen, Sortland, Tjeldsund and Vågan in Nordland county.
