The Brześć Kujawski Voivodeship (Polish: Województwo brzesko-kujawskie, Latin: Palatinatus Brestensis) was a unit of administrative division and local government in the Kingdom of Poland (later Polish–Lithuanian Commonwealth), from the 14th century to the Second Partition of Poland in 1793. It was part of the historic Kuyavia region and the Greater Poland Province. Originally, its name was Brzesc Voivodeship (Województwo brzeskie), but after the 1569 Union of Lublin, it was renamed into Brześć Kujawski Voivodeship, to distinguish it from Lithuanian Brest Litovsk Voivodeship (Polish: Województwo brzesko-litewskie).
