Krab (Russian: Краб, lit. 'Crab') was a submarine minelayer built for the Imperial Russian Navy during the 1910s. Completed in 1915, she served with the Black Sea Fleet during the First World War and executed three war patrols in 1915-16 before going to Sevastopol for repairs. She was scuttled there in 1919 to prevent her capture by the Bolsheviks. The wreck was raised in 1935 and scrapped.
