Eastern Upper Lusatia (German: Östliche Oberlausitz; Upper Sorbian: Wuchodna Hornja Łužica) is a natural region in Saxony and, in a broader sense, part of the Western Sudetes range including the Lower Silesian Voivodeship.
Eastern Upper Lusatia runs in a north-south direction between the towns of Görlitz and Zittau.
Geographical features of particular note in the region are the Königshain Hills, the Neiße valley and the old mining landscapes south of Görlitz and in the Zittau Basin.
Ice age ground moraines, meltwater sands and the overlying loess soils fill out the granite relief to varying degrees.
As witnesses to the Tertiary volcanism of the area there are lava plains and isolated hills of basalt and phonolite.
