ORP Żbik was a Wilk-class submarine which saw service in the Polish Navy from 1932 to 1955.

When World War II began on 1 September 1939, she took part in the Worek Plan for the defense of the Polish coast.

According to the plan she laid her mines, one of which sank a small (525 t) German minesweeper M85 on 1 October.

After suffering battle damage and shortages of fuel, the submarine withdrew to neutral Swedish waters and was interned on 25 September.

After the war, she returned to Poland in October 1945 and served in the navy of the Polish People's Republic until 1955.
