Unas /ˈjuːnəs/ or Wenis, also spelled Unis (Ancient Egyptian: wnjs, hellenized form Oenas /ˈiːnəs/ or Onnos), was a pharaoh, the ninth and last ruler of the Fifth Dynasty of Egypt during the Old Kingdom. Unas reigned for 15 to 30 years in the mid-24th century BC (circa 2345–2315 BC), succeeding Djedkare Isesi, who might have been his father.
Little is known of Unas' activities during his reign, which was a time of economic decline. Egypt maintained trade relations with the Levantine coast and Nubia, and military action may have taken place in southern Canaan. The growth and decentralization of the administration in conjunction with the lessening of the king's power continued under Unas, ultimately contributing to the collapse of the Old Kingdom some 200 years later.
