Husøya[1] is a small island and the administrative centre of Træna Municipality in Nordland county, Norway.
It is located just east of the island of Sanna in the Trænfjorden, about 20 kilometres (12 mi) northwest of the island of Lovund (in neighboring Lurøy Municipality) and about 12 kilometres (7.5 mi) south of Selvær.
The Træna Lighthouse lies south of the island.
[2] Most of the flat island is made up of the village of Husøya, which is the administrative centre of the municipality.
[3] The annual Træna Music Festival is held here and on the neighboring island of Sanna.
