This category brings together articles on the uyezds of Nizhny Novgorod Governorate — administrative-territorial units that existed within the Russian state, the Russian Empire, and the RSFSR up until the reforms of the 1920s. The uyezds covered extensive territories that today make up Nizhny Novgorod Oblast, and differed in their economic structure, geography, and history of settlement.
Among the most thoroughly described are the Nizhny Novgorod Uyezd, centred on the governorate capital, the Arzamas Uyezd, whose history goes back to the 16th century, the Semenovsky Uyezd in the north of the governorate, and the Balakhna Uyezd), which had already taken shape in pre-Petrine times.
