Hansnes is a village located in Norway that serves as the administrative centre of Karlsøy Municipality in Troms county. It is situated on the northeast side of the island of Ringvassøya along the Langsundet strait.
The village is positioned approximately 58 kilometres (36 mi) northeast of the city of Tromsø by car. A significant infrastructure project for the area is the proposed Langsund Tunnel, an undersea tunnel intended to connect the islands of Ringvassøya and Reinøya. Once completed, this tunnel is expected to replace the current ferry service operating from Hansnes to the nearby islands of Karlsøya, Vannøya, and Reinøya.
