The Kars oblast was a province (oblast) of the Caucasus Viceroyalty of the Russian Empire between 1878 and 1917. Its capital was the city of Kars, which later became part of Turkey. The oblast bordered the Ottoman Empire to the west, the Batum Oblast to the north, the Tiflis Governorate to the northeast, and the Erivan Governorate to the east. The Kars oblast included parts of the contemporary provinces of Kars, Ardahan, and Erzurum Province of Turkey, and the Amasia Community of the Shirak Province of Armenia.
