ORP Warszawa was an armed river monitor of the Riverine Flotilla of the Polish Navy, launched in 1920 and scuttled in 1939.

Like all of the ships of the Riverine Flotilla of the Polish Navy in Pinsk, she was not used in combat during the German Invasion of Poland.

After the Soviet invasion of Poland, she was scuttled on the Pripyat River on 18 September 1939,[2] because of the impossibility of withdrawal.

She was raised on 11 October 1939 by the Soviets, towed to Factory No 300 in Kiev, repaired and commissioned as Vitebsk (Витебск).

[1] From July 1941 she fought against the Germans on the Berezina, Desna and Dnieper Rivers, in the defence of Kiev.
