The Caucasus Viceroyalty was the Imperial Russian administrative and political authority in the Caucasus region exercised through the offices of glavnoupravlyayushchiy (1801–1844, 1882–1902) and namestnik (наместник) (1844–1882, 1904–1917). These two terms are commonly, but imprecisely, translated into English as viceroy, which is frequently used interchangeably with governor general. More accurately, glavnoupravlyayushchij is referred to as High Commissioner of the Caucasus, and namestnik as viceroy.
