Radzymin is a town in Poland and is one of the distant suburbs of the city of Warsaw. It is located in the powiat of Woà Âomin 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 dates back to the Middle Ages. It was mentioned in a document of Duke Bolesà Âaw IV of Warsaw from 1440. It was granted a town charter in 1475. Since then, the town shared the fate of the nearby city of Warsaw, located only away. It was a private town owned by Polish nobility, administratively located in the Warsaw County in the Masovian Voivodeship in the Greater Poland Province of the Kingdom of Poland.
It was annexed by Prussia in the Third Partition of Poland in 1795. In 1807, it was regained by Poles and included within the newly formed, however short-lived Duchy of Warsaw. During the AustroâÂÂPolish War of 1809, it was the site of the Battle of Radzymin (1809), which ended in a Polish victory. Following the duchy's dissolution in 1815, the town fell to the Russian Partition of Poland. During the January Uprising, on July 30, 1863, a skirmish between Polish insurgents and Russian soldiers took place there. Russian soldiers surrounded a Polish insurgent unit, but after a short battle the Poles managed to break through the encirclement and escape towards Kaà Âuszyn. Following World War I, in 1918, Poland regained independence and control of the town. During the PolishâÂÂSoviet War, in August 1920, it was the site of the Battle of Radzymin (1920), in which Poles defeated the invading Russians.
Following the joint German-Soviet invasion of Poland, which started World War II in September 1939, the town was occupied by Germany. In August 1944, it was the site of the Battle of Radzymin (1944) between Germany and the advancing Soviet troops.
The Marecka Kolej Dojazdowa () was a narrow gauge railway in Poland connecting Warsaw with Marki and Radzymin active from 1896 to 1974.
The local football club founded in 1923 is Mazur Radzymin. It competes in the lower leagues, and is currently co-funded by one of its players, rapper Quebonafide. In 2025, Mazur signed former Poland internationals Jakub Rzeà ºniczak and Grzegorz Krychowiak.
