Pope Jacob of Alexandria, also known as James, was the 50th Pope of Alexandria and Patriarch of the See of St. Mark from 819 to 830. Pope Jacob ordained Abuna Yohannes as the head of the Ethiopian Orthodox Church, according to the History of the Patriarchs of Alexandria; however, civil war, drought, and plague in Ethiopia forced Yohannes to return to Alexandria, where he remained through Pope Jacob's tenure.
