The Masovian Voivodeship[a] was a voivodeship of the Congress Poland, that existed from 1816 to 1837. Its capital was Warsaw. It was established on 16 January 1816, from the Warsaw Department and the three counties of the Bydgoszcz Department, and existed until 23 February 1837, when it was replaced by the Masovian Governorate.
