Bautzen or Budyšin, until 1868 Budissin in German, is a town in eastern Saxony, Germany, and the administrative centre of the district of Bautzen. It is located on the Spree river, is the eighth most populous town in Saxony, and is the seat of Saxony's largest district. Bautzen lies in the bilingual Sorbian settlement area of Lusatia, and is Lusatia's third-largest town after Cottbus and Görlitz, as well as the second-largest town in Upper Lusatia.

Upper Sorbian, occasionally referred to as Wendish, is a minority language spoken by Sorbs, in the historical province of Upper Lusatia, which is today part of Saxony, Germany. It is grouped in the West Slavic language branch, together with Lower Sorbian, Czech, Polish, Slovak and Kashubian.
