Ochakov was a Kara-class cruiser of the Russian Navy Black Sea Fleet.

She was decommissioned in 2011 but remained laid-up in Sevastopol, until on 3 March 2014 she was towed and sunk as a blockship in the channel to Donuzlav lake, in Novoozerne, in western Crimea.

The ship was constructed in the 61 Kommunar Shipyard at Nikolayev (Mykolaiv) on the Black Sea.

[5] On 20 August 2011, the naval flag of Ochakov was hauled down and the ship prepared to be sold for scrap.

[6][7] On 6 March 2014, during the annexation of Crimea by the Russian Federation, Russian sailors scuttled the hull of Ochakov in Donuzlav Lake at the entrance to Donuzlav Bay in western Crimea as a blockship, in an attempt to prevent Ukrainian Navy ships from gaining access to the Black Sea.
