The Vilayet of Diyâr-ı Bekr (Armenian: Տիգրանակերտի նահանգ, Ottoman Turkish: ولايت ديار بكر, Vilâyet-i Diyarbakır) was a first-level administrative division (vilayet) of the Ottoman Empire, wholly located within what is now modern Turkey. The vilayet extended south from Palu on the Euphrates to Mardin and Nusaybin on the edge of the Mesopotamian plain. After the establishment of Republic of Turkey in 1923, the region was incorporated into the newly created state.
