Podkarpackie Voivodeship or Podkarpackie Province (in Polish: województwo podkarpackie [vɔjɛˈvut͡stfɔ pɔtkarˈpatskʲɛ]), also known as Subcarpathian Voivodeship or Subcarpathia Province, is a voivodeship, or province, in extreme-southeastern Poland. Its administrative capital and largest city is Rzeszów. (Historically Lwów was the administrative center of this part of Poland, but after 1945, when Lwów became part of the Soviet Union, that city's role was relinquished to Rzeszów).
The voivodeship was created on 1 January 1999 out of the former Rzeszów, Przemyśl, Krosno and (partially) Tarnów and Tarnobrzeg Voivodeships, pursuant to the Polish local-government reforms adopted in 1998.
