Eastphalia (German: Ostfalen; 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 Leine river in the west as well as Elbe and Saale in the east. The territory corresponds with the southeastern part of the present-day state of Lower Saxony and western Saxony-Anhalt. Together with Westphalia, central Angria and Nordalbingia it was one of the four Saxon main administrative regions.
The name Ostfalen probably means "east plain". Falen is a Germanic word meaning "flat", "level" and "plain" and is related to the Old Swedish word fala, found today in place names such as Falbygden and Falun, as well as in the northern German town of Fallstedt. The North German Plain of Eastphalia and Westphalia, divided by the Weser river, stand in contrast to the hilly region to the south, the Central Uplands of Franconia and Thuringia. Unlike the name Westphalia, that was perpetuated by the Duchy of Westphalia held by the Archbishops of Cologne, the name Eastphalia gradually fell out of use when the Saxon stem duchy dissolved upon the deposition of Duke Henry the Lion in 1180.
German linguists reintroduced the term in the 19th century in the course of researching the Eastphalian language as a West Low German dialect. With the rise of scientific racism in the 19th and early 20th century, mention began to be made – notably by Hans F. K. Günther – of a "Phalian" subtype (fälische Rasse) of an "Aryan race" according to the occult concept of Helena Blavatsky and her Ariosophic followers.
With Charlemagne's defeat and baptism of Duke Widukind in 785 during the Saxon Wars, his lands were integrated into the Frankish Empire and the Saxons were increasingly converted to Christianity. The bishoprics of Halberstadt and Hildesheim were established in eastern Saxony, bounded by the Oker river, in 804 and 815 respectively. The medieval Duchy of Saxony was divided between the districts of Eastphalia (Ostfalahi), Westphalia and Engern.
The Eastphalian territory at the Harz mountain range was the hereditary lands of Henry the Fowler, the first Saxon duke to become King of the Romans in 919, and his descendants of the Ottonian dynasty. They left several Romanesque abbeys and castles, a cultural landscape that today encompasses three World Heritage Sites with the medieval town of Goslar and Quedlinburg, as well as St. Mary's Cathedral and St. Michael's Church at Hildesheim. As the Eastphalian territory bordered on the lands of the Polabian Slavs beyond the Elbe and Saale rivers, it became the starting point of the German Ostsiedlung, started by the invasions of King Henry and continued by the Saxon margraves.
After the Welf duke Henry the Lion was placed under Imperial ban in 1180, Eastphalia was increasingly subdivided into smaller states, foremost the Welf Duchy of Brunswick-Lüneburg and the counties of Anhalt, Wernigerode and Blankenburg as well as the Imperial city of Goslar, but also the ecclesiastical territories of the Archbishopric of Magdeburg, the prince-bishoprics of Hildesheim and Halberstadt and Quedlinburg Abbey. The Saxon tradition was perpetuated by the Ascanian dukes of Saxe-Wittenberg, who secured for themselves the electoral dignity and later established the Electorate of Saxony on the upper Elbe.

- Gretinge (Hohne)
- Balsamgau (Stendal)
- Astfala (Hildesheim)
