Endaruta was the ruler of Achshaph-(Akšapa of the letters), in the 1350-1335 BC Amarna letters correspondence. Endaruta was the author of EA 223, (EA for 'el Amarna'), of the letters. He is only referenced in two other letters EA 366 and 367, but EA 367, entitled: "From the Pharaoh to a vassal" is addressed to Endaruta, with instructions to guard his city. Pharaoh states Hanni–Khanni, is en route with the "archer-army force", and to prepare for their needs. Tablet-letter 367 is an undamaged, twenty-five line letter.
