Greater Poland Province (Polish: Prowincja Wielkopolska) was an administrative division of the Crown of the Kingdom of Poland from 1569 until 1795.

The name of the province comes from the historic land of Greater Poland.

The Greater Poland Province consisted initially of twelve voivodeships (after 1768 thirteen voivodeships)[2] and one duchy: The location of the Crown Tribunal for the Greater Poland Province (the highest appeal court of the province) was Piotrków Trybunalski, and after the Convocation Sejm (1764) also Poznań and Bydgoszcz.

The five most influential cities, i.e. Warsaw, Poznań, Gdańsk, Toruń and Elbląg, enjoyed voting rights during the Royal elections.
