Eastphalia (German: Ostfalen [ɔstˈfaːlən]; Eastphalian: Oostfalen) is a historical region in northern Germany, encompassing the eastern Gaue (shires) of the historic stem duchy of Saxony, roughly confined by the River Leine in the west and the Elbe and Saale in the east. The territory corresponds with modern southeastern Lower Saxony, western Saxony-Anhalt, and northern Thuringia. Together with Westphalia, Angria, and Nordalbingia, it was one of the four main Saxon administrative regions.
