Rain is a town in the Donau-Ries district, in Bavaria, Germany. It is situated on the river Lech, close to its confluence with the Danube, 11 km east of Donauwörth.
Rain is on the B16 road and served by the Ingolstadt–Neuoffingen railway, both of which run between Ulm and Regensburg.
The earliest reference to Rain is in a document of the Niederschönenfeld monastery dated 4 July 1257, wherein it is described as a "civitas nostra" or ducal town. It is most probable that Rain was founded during the reign of Otto II Wittelsbach, Duke of Bavaria or at the latest in the reign of Louis II, Duke of Bavaria before 1257.
