Upper Lusatia is a historical region in Germany and Poland. Along with Lower Lusatia to the north, it makes up the region of Lusatia, named after the Slavic Lusici tribe. Both Lusatias are home to the West Slavic minority group of the Sorbs.
The major part of Upper Lusatia belongs to the German state of Saxony, roughly comprising the Bautzen and Görlitz districts. The northwestern extremity around Ruhland and Tettau is incorporated into the Oberspreewald-Lausitz district of Brandenburg. The Polish part, east of the Neisse River, belongs to Lower Silesian Voivodeship. A small strip of land in the north around Łęknica, together with the Polish part of Lower Lusatia, is incorporated into Lubusz Voivodeship.
