The Vilayet of Mamuret-ul-Aziz, also referred to as Harput Vilayet (Armenian: Խարբերդի վիլայեթ Kharberdi Vilayet’) was a first-level administrative division (vilayet) of the Ottoman Empire in the late 19th and early 20th centuries. It was also one of the Six vilayets. The vilayet was located between Euphrates and Murat river valleys. To the northwest was Sivas Vilayet.
