Nowe Miasteczko [ˈnɔvɛ mʲasˈtɛt͡ʂkɔ] (German: Neustädtel) is a town in Nowa Sól County, Lubusz Voivodeship, in western Poland, with 2,756 inhabitants (2019).

The area became part of the emerging Polish state in the 10th century, and following the Poland's fragmentation into smaller provincial duchies, it was part of the duchies of Silesia and Głogów. The town was first mentioned in a document of Henry III, Duke of Głogów from 1296, and was granted town rights before that date. In the 18th century, one of two main routes connecting Warsaw and Dresden ran through the town and Kings Augustus II the Strong and Augustus III of Poland traveled that route numerous times.
