Poznań Voivodeship was the name of several former administrative regions (województwo, rendered as voivodeship and usually translated as "province") in Poland, centered on the city of Poznań, although the exact boundaries changed over the years. Poznań Voivodeship was incorporated into the Greater Poland Voivodeship after the Polish local government reforms of 1998.
