Acilisene, known as Ekegheats or Yekeghyats in Armenian, was a region of the Upper Armenia province of historical Armenia. It was a strip of land along the Upper Euphrates or Arsanias roughly corresponding to today's Erzincan Province of Turkey. Its main cities were Erznka and Ani-Kamakh near the ancient necropolis of the Arsacid kings of Armenia. According to Strabo, Acilisene was situated along the Euphrates between Derxene and the river's bend near Dostal, while in the south it bordered on Sophene. Hellenistic Acilisene constituted a considerably vaster district than it would later become, encompassing the territories that would eventually be subdivided into the cantons of Aghyun, Daranali, Mananaghi, Mzur, and Yekeghyats.
