The Erivan uezd was a county (uezd) of the Erivan Governorate of the Caucasus Viceroyalty of the Russian Empire. The uezd bordered the Etchmiadzin and Surmalu uezds to the west, the Nor Bayazet uezd to the east, the Sharur-Daralayaz uezd to the south, and Iran to the southwest. It included most of the Ararat Province and southern parts of the Kotayk Province of central Armenia, the Sadarak District of the Nakhchivan exclave of Azerbaijan, and the Aras corridor of the Aralık District of the Iğdır Province of Turkey. The administrative center of the Erivan uezd was the city of Erivan (present-day Yerevan, the capital of Armenia).
