Saint Petersburg Governorate (Russian: Санкт-Петербу́ргская губе́рния, Sankt-Peterburgskaya guberniya), or Government of Saint Petersburg, was an administrative division (a guberniya) of the Tsardom of Russia, the Russian Empire, and the Russian SFSR, which existed in 1708–1927.
The governorate, together with seven other governorates, was established by Tsar Peter the Great's edict as Ingermanland Governorate (Ингерманла́ндская губе́рния, Ingermanlandskaya guberniya) on December 29 [O.S. December 18], 1708 on the territories conquered from the Swedish Empire in the Great Northern War. As with the rest of the governorates, neither the borders nor internal subdivisions of Ingermanland Governorate were defined; instead, the territory was defined as a set of cities and the lands adjacent to those cities.
By another edict on June 3, 1710, the governorate was renamed St. Petersburg Governorate after the newly founded city of Saint Petersburg, and in 1721 the former Swedish Duchy of Ingria, and parts of the County of Kexholm and the County of Viborg and Nyslott were formally ceded to Russia in the Treaty of Nystad. After the Treaty of Åbo in 1743, the parts of Kexholm and Viborg were joined with new territorial gains from Sweden into the Governorate of Vyborg (Russian: Выборгская губерния).
