The Kola Peninsula is a peninsula in the far northwest of Russia. Constituting the bulk of the territory of Murmansk Oblast, it lies almost completely inside the Arctic Circle and is bordered by the Barents Sea in the north and the White Sea in the east and southeast. The city of Murmansk is the most populous human settlement on the peninsula, with a population of over 300,000 as of the 2010 Census.

Despite the peninsula's northerly location, its proximity to the Gulf Stream leads to unusually high temperatures in winter but also results in high winds due to the temperature variations between land and the Barents Sea. Summers are rather chilly, with the average July temperature of only 11 °C (52 °F). The peninsula is covered by taiga in the south and tundra in the north, where permafrost limits the growth of the trees resulting in a landscape dominated by shrubs and grasses.
