Zikirti or Zikirtu, (also: Zikirta, Zikurti, Zekertu) was an ancient kingdom (750-521 BC), in northern Zagros, which comprised the easternmost part of Greater Mannae. Geographically it corresponds with the modern counties of Takab and Shahindej in northwestern Iran.
The people of Zikirti are possibly to be identified with ancient Iranian Sagartians, mentioned by Herodotus.
