Silesian Voivodeship, or Silesia Province (in Polish, województwo slaskie ), is a voivodeship, or province, in southern Poland, centering on the historic region known as Upper Silesia (Górny Slask), with the capital in Katowice. Contrary to the name, however, the eastern half of the Silesian Voivodeship is not identical to the historical region of Silesia, but rather that of Lesser Poland.
