Silesian German (Silesian German: Schläsche Sproache/Schläs'sche Sproche, German: Schlesisch) or Lower Silesian is a nearly extinct German dialect spoken in Silesia. Today, the region of Silesia has been incorporated into southwestern Poland, with smaller portions in northeastern Czech Republic and in eastern Germany.
Today, Silesian German is a dialect spoken in Upper Lusatia, the part of Silesia west of the Oder–Neisse line that remained German after 1945.
The German Silesian dialect is not recognized by the Polish State in any way, although the status of the German minority in Poland has improved much since the 1991 communist collapse and Polish entry into the European Union. It can be divided into Gebirgsschlesische Dialektgruppe, Südostschlesische Dialektgruppe, mittelschlesische Dialektgruppe, westschlesische Dialektgruppe and niederländische Dialektgruppe. The nordostböhmische Dialektgruppe belongs to Silesian, too.
