Lubusz Voivodeship, or Lubuskie Province (Polish: województwo lubuskie [vɔjɛˈvut͡stfɔ luˈbuskʲɛ]), is a voivodeship (province) in western Poland. It was created on January 1, 1999, out of the former Gorzów Wielkopolski and Zielona Góra Voivodeships, pursuant to the Polish local government reforms adopted in 1998. The province's name recalls the historic Lubusz Land (Lebus or Lubus), although parts of the voivodeship belong to the historic regions of Silesia, Greater Poland and Lusatia. Until 1945, it mainly formed the Neumark within the Prussian Province of Brandenburg.
