Murmansk Oblast

Murmansk Oblast is a federal subject (an oblast) of Russia, located in the northwestern part of the country, with a total land area of 144,900 square kilometres (55,900 sq mi). Its only internal border is the Republic of Karelia to the south, and it is bordered internationally by Finland to the west and Norway to the northwest and the Barents Sea lies to the north and White Sea lies to the south and east. Its administrative center is the city of Murmansk. As of the 2010 Census, its population was 795,409; however, at the 2021 Census, the population had declined to 667,744.

Geographically, Murmansk Oblast is located mainly on the Kola Peninsula almost completely north of the Arctic Circle and is a part of the larger Sápmi (Lapland) region that spans over four countries. The oblast borders with the Republic of Karelia in Russia in the south, Lapland Region in Finland in the west, Finnmark County in Norway in the northwest, and is bounded by the Barents Sea in the north and the White Sea in the south and east. Arkhangelsk Oblast of Russia lies across the White Sea.

Much of the oblast's relief is hilly, with the Khibiny and Lovozero ranges rising as high as 1,200 meters (3,900 ft) above sea level and stretching from west to east. The highest point of Murmansk Oblast is Yudychvumchorr, a flat-topped peak of the Khibiny. The north of the oblast is mostly covered by tundra; forest-tundra prevails further south, while the southern regions are in the taiga zone. There are over 100,000 lakes and 18,000 rivers in the oblast. The coast contains the Rybachy Peninsula and the Cape Svyatoy Nos peninsulas.

The climate is harsh and unstable, due to the proximity of the Gulf Stream on one side and Arctic cold fronts on the other. Sharp temperature changes, high winds, and abundant precipitation are common throughout the year, with the heating season lasting for ten straight months. However, the waters of the Murman Coast in the south remain warm enough to remain ice-free even in winter.

There is also a large number of islands belonging to the oblast, the main ones being (west to east) the Aynovy Islands, Bolshoy Oleny Island, Kildin Island Malyy Oleniy Island, Kharlov Island, Vesknyak Island, Litskiye Island, Nokuyev Island, Vitte Island, Lumbovskiy Island, Goryainov Island and Sosnovets Island.

Most areas of the Kola Peninsula are subarctic climate (Köppen climate classification: Dfc). The nearby islands usually belong to tundra (Köppen climate classification: ET).

The Saami, now a very small minority, are the indigenous people of the region. Russians started exploring the shores of the White Sea as early as in the 12th century, and in 1916 during World War I founded the Russian city of Murmansk as an ice-free supply port. As of 2010, Murmansk had 307,257 (2010 census), people – nearly 40% of the oblast's population. Many Finns also immigrated to Murmansk during the Finnish famine, around the year 1860.

The oblast was established on May 28, 1938 from Murmansk Okrug of Leningrad Oblast (comprising the city of Murmansk, Kirovsky, Kolsky, Lovozersky, Polyarny, Saamsky, Teribersky, and Tersky Districts) and Kandalakshsky District of the Karelian ASSR.
