Until it lost its city rights, the village was known as Nowe Miasto Korczyn ("New Town Korczyn"). During its existence, Nowy Korczyn was also known as "Khadash", "Nayshtut", "Neustadt", "Novi Kochin", and "Novi Kortchin". It was established before 1258 by Boleslaus the Chaste, and used to be an important trade and political center. From the 15th century onwards the General Assembly of Lesser Poland was held there. In the 17th century the town began a decline, and lost its city status in 1869. Up until the Second World War, Nowy Korczyn, by now a village, had a large Jewish community, many of whom perished in the Holocaust.
