Lurøy is a municipality in Nordland county, Norway. It is part of the Helgeland traditional region. The administrative centre of the municipality is the village of Lurøy, located on the island of Lurøya. Other villages include Aldra, Haugland, Konsvikosen, Lovund, Sleneset, Stokkvågen, and Tonnes.
The municipality is located on the coast just south of the Arctic circle, on the western edge of the Saltfjellet mountain range. The Lurøygården (Lurøy Farm) on Lurøya is a more than 200 year old renaissance garden with old plants, a pool, and a nearly 20-metre (66 ft) high Copper Beech.
The municipality (originally the parish) is named after the island of Lurøya (Old Norse: Lúðrøy), since the first church was built there. The first element is lúðr which means "hollowed log" (here probably referring to the form of the mountain of the island). The last element is øy which means "island".
