The Saxon Loess Fields refer to a natural region that lies mainly within the state of Saxony in central Germany. In addition, small areas of this region extend to the northwest and west into Saxony-Anhalt, to the southeast into Thuringia and to the northeast into Brandenburg. It more-or-less combines the BfN's major regions listed as D19 Saxon Upland and Ore Mountain Foreland, and D14, Upper Lusatia (Oberlausitz); only the range of Central Uplands hills, the Lusatian Mountains, has been excluded and instead forms part of the Saxon Highlands and Uplands.
