Radzymin [raˈd͡zɨmʲin] is a town in Poland and is one of the distant suburbs of the city of Warsaw. It is located in the powiat of Wołomin of the Masovian Voivodeship. The town has 8,818 inhabitants (as of 2008, but the surrounding commune is heavily populated and has an additional 11,000 inhabitants).
Radzymin was founded by Bolesław IV of Warsaw in 1440. It was granted a town charter in 1475. Since then, the town shared the fate of the nearby city of Warsaw, located only 25 kilometers (16 mi) away. The town is notable for two major battles that took place there in the 20th century − the Battle of Radzymin (1920) and Battle of Radzymin (1944).
