Podlaskie Voivodeship is a voivodeship in northeastern Poland. The name of the voivodeship refers to the historical region of Podlachia (in Polish, Podlasie), and significant part of its territory corresponds to that region. The capital and largest city is Białystok.
It borders the Masovian Voivodeship to the west, Warmian-Masurian Voivodeship to the northwest, Lublin Voivodeship to the south, Belarus to the east, and Lithuania to the northeast.
The voivodeship was created on 1 January 1999, pursuant to the Polish local government reforms adopted in 1998, from the former Białystok and Łomża Voivodeships and the eastern half of the former Suwałki Voivodeship.
