Iyasu I or Joshua I, also known as Iyasu the Great, is nəgusä nägäst (throne name Adyam Sagad, "to whom the confines of the earth bow"; 19 July 1682 - 13 October 1706) of Ethiopia, and a member of the Solomonic dynasty.
He is the son of Yohannes I and Empress Sabla Wangel.
According to G.W.B Huntingford, Iyasu "owed his reputation partly to the mildness of his character, exemplified in his treatment of the princes on Wehni in his first year, and his attention to religious matters, and partly to his abdication, retirement, and murder."
