The rank of '''Admiral of the Fleet of the Soviet Union''' (Russian: ''Admiral Flota Sovietskogo Soyuza'', Адмирал Флота Советского Союза) was the highest naval rank of the Soviet Union.  

The rank was largely honorary and could be considered equivalent to Admiral of the Fleet (Адмирал флота) that was already equivalent to the Marshal of the Soviet Union since 1945. The holders were entitled to a Marshal's Star.

Upon its creation, the only two Admirals of the Fleet, Nikolai Kuznetsov and Ivan Isakov, were "promoted" to this rank. Less than a year later Kuznetsov was demoted to Vice Admiral for political reasons in 1956 and Isakov remained the only Admiral of the Fleet of the Soviet Union until his death in 1967. His successor, Admiral Sergei Gorshkov, then became the third and final Admiral of the Fleet of the Soviet Union. Gorshkov died in 1988 and no further appointments were made before the fall of the Soviet Union in 1991.

From Admiral of the Fleet, which was recreated as an intermediate rank, equivalent to General of the Army.
