ORP Gryf (English: "Griffin") was a large Polish Navy minelayer, sunk during the 1939 German invasion of Poland. She was one of two large Polish ships that were not evacuated to Great Britain during Operation Peking prior to the outbreak of the Polish Defensive War (Wicher was the other). After taking aboard naval mines from a floating depot, the flotilla headed for Hel Peninsula, assisted by ORP Wicher and two gunboats. En route she was attacked by a squadron of 33 German Ju 87B dive bombers and damaged with several close misses. Although the damages were minor, the ship lost 22 sailors, including its captain Lt Cmdr Stefan Kwiatkowski
