Bitlis Vilayet (Armenian: Բիթլիսի վիլայեթ Bit'lisi vilayet' Ottoman Turkish: ولایت بتليس) was a first-level administrative division (vilayet) of the Ottoman Empire. Before the Russo-Turkish War (1877–1878) it had been part of the Erzurum Vilayet, it was then made a separate vilayet by the Porte. It was one of the six Armenian vilayets of the Empire.
At the beginning of the 20th century it reportedly had an area of 11,522 square miles (29,840 km2), while the preliminary results of the first Ottoman census of 1885 (published in 1908) gave the population as 388,625. The accuracy of the population figures ranges from "approximate" to "merely conjectural" depending on the region from which they were gathered.
