The Battle of Kock, was the final battle of the Invasion of Poland at the beginning of World War II. It took place from October 2 through October 5, 1939, near the town of Kock, Poland.

The Polish Independent Operational Group Polesie, led by General Franciszek Kleeberg, fought the German 14th Motorised Corps, led by General Gustav von Wiedesheim.

The Polish battle plan was disorganized, but with few officers left this was expected. The Wehrmacht destroyed the Polish reserve Army Prusy and forced them to withdraw. With heavy losses, the Polish armies retreated to Kraków and the Vistula river. From there, they took the route from Warsaw to Sandomierz. From Sandomierz, they were able to move on to the Lublin area.
