The Erivan Governorate was a province (guberniya) of the Caucasus Viceroyalty of the Russian Empire, with its centеr in Erivan. Its area was 27,830 sq. kilometеrs, roughly corresponding to what is now most of central Armenia, the Iğdır Province of Turkey, and the Nakhchivan exclave of Azerbaijan. At the end of the 19th century, it bordered the Tiflis Governorate to the north, the Elizavetpol Governorate to the east, the Kars Oblast to the west, and Persia and the Ottoman Empire to the south. Mount Ararat and the fertile Ararat Valley were included in the center of the province.

The Caucasus Viceroyalty was the Russian Empire's administrative and political authority in the Caucasus region exercised through the offices of glavnoupravlyayushchiy and namestnik ("viceroy"), situated in the modern areas of the Russian Federation, Armenia, Azerbaijan and Georgia. These two terms are commonly, but imprecisely, translated into English as viceroy, which is frequently used interchangeably with governor general. More accurately, glavnoupravlyayushchiy is referred to as the High Commissioner of the Caucasus, and namestnik as Viceroy.
