Fidonisy () was the name ship of her class of eight destroyers built for the Imperial Russian Navy during World War I. Originally named Feodonisy (), she was renamed Fidonisy before she was completed. Completed in 1917, she played a minor role in the war as part of the Black Sea Fleet before the Russian Revolution began later that year. Her crew joined the Bolsheviks in December and she supported their efforts to assert control in the Crimea over the next several months. The ship sailed from Sevastopol as the Germans approached in May 1918, but was scuttled in Novorossiysk harbor the following month when the Germans demanded that she be handed over as per the terms of the Treaty of Brest-Litovsk. Her wreck was discovered in 1964 and was partially salvaged.
