Norway, country in northern Europe, in the region called Scandinavia. A long and mostly narrow country, Norway occupies the western portion of the Scandinavian Peninsula. Norway’s extensive coastline is washed on three sides by seas. To the north is the Barents Sea, an arm of the Arctic Ocean; to the west is the Norwegian Sea; and to the south are the Skagerrak, a strait separating Norway from Denmark, and the North Sea. Norway shares a long eastern border with Sweden, and in the far northeast Norway shares a frontier with Russia and Finland. Oslo, in the southeast, is Norway’s capital and largest city.
