The Caucasus Viceroyalty was the Imperial Russia administrative and political authority in the Caucasus region exercised through the offices of glavnoupravlyayushchiy (Russian: главноуправляющий) (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, glavnoupravljajuçij is referred to as High Commissioner of the Caucasus, and namestnik as Viceroy.
