The Polish 4th Infantry Division (Polish: 4. Dywizja Piechoty) was created following Polish independence after the end of World War I. The division participated in the Polish–Ukrainian War in 1919. During World War II, the division existed as three wholly separate organizations, the original incarnation of the division as part of the pre-war Polish Army, the second incarnation armed and equipped by the western Allies, and another division armed and equipped and controlled by the Soviet Union. The second and third incarnations of this division existed simultaneously from 1944 until 1947.
