The Pomeranian Griffin secret military organization (Polish: Tajna Organizacja Wojskowa Gryf Pomorski) was a Polish anti-Nazi resistance group active in Pomerania and East Prussia during World War II. A major Polish resistance organization in the Pomerania region, at its height in 1943 it might have had as many as 20,000 members, although only about 500 were active partisans in the forests (leśni). The name of the organization referred to the traditional coat of arms of Pomerania, which consists of either the black (for Gdansk Pomerania) or the red (for Western Pomerania) griffin.
