The Baltic Fleet (Russian: Балтийский флот, translit. Baltiyskiy flot) is the fleet of the Russian Navy in the Baltic Sea.

Established 18 May 1703, under Tsar Peter the Great as part of the Imperial Russian Navy, the Baltic Fleet is the oldest Russian Navy formation. In 1918 the fleet was inherited by the Russian SFSR then the Soviet Union in 1922, where it was eventually known as the Twice Red Banner Baltic Fleet as part of the Soviet Navy, as during this period it gained the two awards of the Order of the Red Banner. Following the collapse of the Soviet Union in 1991, the Baltic Fleet was inherited by the Russian Federation and reverted to its original name as part of the Russian Navy.

The Baltic Fleet is headquartered in Kaliningrad and its main base in Baltiysk (Pillau), both in Kaliningrad Oblast, and another base in Kronstadt, Saint Petersburg in the Gulf of Finland.
