'''Hadad-yith'i''' (, ) was governor of Guzana and Sikani in northern Syria (c. 850 BCE). A client king or vassal of the Neo-Assyrian Empire, he was the son of Sassu-nuri, who also served as governor before him. Knowledge of Hadad-yith'i's rule comes largely from the statue and its inscription found at the Tell Fekheriye. Known as the Hadad-yith'i bilingual inscription, as it is written in both Old Aramaic and Akkadian, its discovery, decipherment and study contributes significantly to cultural and linguistic understandings of the region.
