Sawīris ibn al-Muqaffaʿ was a tenth-century Coptic Orthodox bishop, historian, and theologian from Egypt. Serving as the bishop of Hermopolis Magna, he lived during the era of the Fatimid Caliphate. He is recognized for his significant contributions to Christian literature, specifically for being the first Coptic author to write theological works in Arabic. This transition to Arabic occurred as the Coptic language began to decline among the local Christian population. He was noted for his ability to defend Christian doctrine through debate within the Fatimid courts.
