Murmansk (Russian: Мурманск) is a port city and the administrative center of Murmansk Oblast in the far northwest part of Russia. It is the world's largest city north of the Arctic Circle and sits on both slopes and banks of a modest fjord, Kola Bay, an estuarine inlet of the Barents Sea, with its bulk on the east bank of the inlet. The city is a major port of the Arctic Ocean and is about 100 kilometres (62 mi) from the border with Norway, 180 kilometres (110 mi) from the border with Finland and 1,930 kilometres (1,200 mi) from Moscow.
Benefiting from the North Atlantic Current, Murmansk resembles cities of its size across western Russia, with highway and railway access to the rest of Europe, and the northernmost trolleybus system on Earth. Its connectivity contrasts with the isolation of Arctic ports like the Siberian Dikson on the shores of the Kara Sea, and Iqaluit, in the Canadian Arctic. Despite long, snowy winters, Murmansk's climate is moderated by the generally ice-free waters around it.
Although there was a building boom in the early twentieth century's arms races, Murmansk's population has been in decline since the Cold War, from 468,039 (1989 Soviet census); 336,137 (2002 Census); 307,257 (2010 Census); to 270,384 (2021 Census).
