Siberia Governorate was an administrative-territorial unit (guberniya) of the Tsardom of Russia and the Russian Empire, which existed from 1708 until 1782. Its seat was in Tobolsk. The governorate was located in the east of Russian Empire and bordered China in the south, Kazan Governorate in the southwest, and Archangelgorod Governorate in the northwest. In the north and the east, the governorate was limited by the seas of the Arctic and Pacific Oceans. In terms of area, Siberia Governorate was by far the biggest of all the governorates, as it included areas in the Urals, Siberia, and the Russian Far East some of which were not yet even settled by Russians at the time.
