Årsteinen is an island in the Norwegian county of Nordland Vågan municipality and belongs to the Lofoten Islands. The Sound Raftsund, which cuts through the Lofoten Islands at its widest point, starts here in the west of the island. The southern tip of Norway's second largest island Hinnøya is located in the north. Årsteinen is achieved through the Digermulen Hinnøya on a dirt track leading to the main town on the southeastern tip of Årsteinen.
The island attracted once the Kaiser Wilhelm II, who was known for his enthusiasm for Norway. Towards the end of the 19th Century, the Kaiser held several summers here with his entourage and ascended the mountain, among others Digermulen. A modest memorial stone for him otherwise he left behind in the capital.
