Athura (Old Persian: 𐎠𐎰𐎢𐎼𐎠 Aθurā) was a geographical area within the Persian Achaemenid Empire held by the last nobility of Aššur (Akkadian), known as Athura (Neo-Aramaic) or Atouria (Greek), during the period of 539 BC to 330 BC as a military protectorate state of Persia under the rule of Cyrus the Great. Although sometimes regarded as a satrapy, Achaemenid royal inscriptions list it as a dahyu, a concept generally interpreted as meaning either a group of people or both a country and its people, without any administrative implication.
