Under the terms of the Svalbard Treaty, international diplomacy recognizes Norwegian sovereignty over Arctic archipelago Svalbard, and designates it as demilitarized.

The Svalbard Treaty recognises the sovereignty of Norway over the Arctic archipelago of Svalbard, at the time called Spitsbergen. The exercise of sovereignty is, however, subject to certain stipulations, and not all Norwegian law applies. The treaty restricts military uses of the archipelago, but it is not demilitarized. The signatories were given equal rights to engage in commercial activities on the islands. As of 2024, Norway and Russia make use of this right.

Svalbard, previously known as Spitsbergen or Spitzbergen, is a Norwegian archipelago that lies at the convergence of the Arctic Ocean with the Atlantic Ocean. North of mainland Europe, it lies about midway between the northern coast of Norway and the North Pole. The islands of the group range from 74° to 81° north latitude, and from 10° to 35° east longitude. The largest island is Spitsbergen, followed in size by Nordaustlandet, Edgeøya, and Barentsøya. Bjørnøya or Bear Island is the most southerly island in the territory, situated some 147 km south of Spitsbergen. Other small islands in the group include Hopen to the southeast of Edgeøya, Kongsøya and Svenskøya in the east, and Kvitøya to the northeast. The largest settlement is Longyearbyen, situated in Isfjorden on the west coast of Spitsbergen.

A demilitarized zone is an area in which treaties or agreements between states, military powers or contending groups forbid military installations, activities, or personnel. A DZ often lies along an established frontier or boundary between two or more military powers or alliances. A DZ may sometimes form a de facto international border, such as the Korean Demilitarized Zone. Other examples of demilitarized zones are a 14 km (8.7 mi) wide area between Iraq and Kuwait; Antarctica ; and outer space.
