Norway (Norwegian: Norge or Noreg (nynorsk)), officially the Kingdom of Norway, is a country and constitutional monarchy in Northern Europe that occupies the western portion of the Scandinavian Peninsula. It is bordered by Sweden, Finland, and Russia, while United Kingdom and the Faroe Islands lies to its west across the North Sea. The country's extensive coastline along the North Atlantic Ocean is home to its famous fjords. The Kingdom of Norway also includes the Arctic island territories of Svalbard and Jan Mayen. Norwegian sovereignty over Svalbard is based upon the Svalbard Treaty, but that treaty does not apply to Jan Mayen. Bouvet Island in the South Atlantic Ocean and Peter I Island and Queen Maud Land in Antarctica are external dependencies, but those three entities do not form part of the kingdom.
