Northern Norway is a geographical region of Norway, consisting of the three northernmost counties Nordland, Troms and Finnmark, in total about 35% of the Norwegian mainland. Some of the largest towns in Northern Norway are Mo i Rana, Bodø, Narvik, Harstad, Tromsø and Alta. Northern Norway is often described as the land of the midnight sun and the land of the northern lights. Farther north, halfway to the North Pole, is the Arctic archipelago of Svalbard, traditionally not regarded as part of Northern Norway.
