Silesian Voivodeship or Silesia Province is a voivodeship, or province, in southern Poland centered on the historic region known as Upper Silesia, with Katowice serving as its capital.
Despite the Silesian Voivodeship's name, most of the historic Silesia region lies outside the present Silesian Voivodeship – divided among Lubusz, Lower Silesian, and Opole Voivodeships. The eastern half of Silesian Voivodeship was historically part of Lesser Poland.
The Voivodeship was created on 1 January 1999 out of the former Katowice, Częstochowa and Bielsko-Biała Voivodeships, pursuant to the Polish local government reforms adopted in 1998.
