In the Russian Federation, a city of federal importance (), also known as a federal city, is a city that has a status of both an inhabited locality and a constituent federal subject. Russia has three federal cities: Moscow, Saint Petersburg, and Sevastopol, which was annexed in 2014 but remains internationally recognised as part of Ukraine.
Moscow and Saint Petersburg are the largest cities in the country: Moscow is the national capital and Saint Petersburg is a former Russian capital and an important port city by the Baltic Sea. Currently, Sevastopol houses the Sevastopol Naval Base, the main port of the Russian Black Sea Fleet.
