Pope Shenouda III (Egyptian Arabic pronunciation: [ʃeˈnuːdæ]; Coptic: Ⲡⲁⲡⲁ Ⲁⲃⲃⲁ Ϣⲉⲛⲟⲩϯ ⲅ̅ Papa Abba Šenoude pimah šoumt; Arabic: بابا الإسكندرية شنودة الثالث Bābā al-Iskandarīyah Shinūdah al-Thālith; 3 August 1923 – 17 March 2012) was the 117th Pope of Alexandria and Patriarch of the See of St. Mark. His papacy lasted 40 years, 4 months, and 4 days from 14 November 1971 until his repose.

His official title was Pope of Alexandria and the Patriarch of All Africa on the Holy Apostolic Throne of Saint Mark the Evangelist, Father of fathers, Shepherd of shepherds, Successor of Saint Mark, thirteenth among the Apostles, Ecumenical Judge, Beloved of Christ. He was also the head of the Holy Synod of the Coptic Orthodox Church. He was a conservative figure within the Church and was also respected within the Muslim community.He became a monk in 1954 under the name Father Antonios the Syrian after joining the Syrian Monastery of the Ever-Virgin Mary the Theotokos. In 1958, he was elevated to the priesthood. In 1962, Pope Cyril VI summoned Fr. Antonios and consecrated him General Bishop for Christian Education and as Dean of the Coptic Orthodox Theological Seminary, whereupon he assumed the papal name Shenouda, which was the name of the Coptic saint Shenoute the Archimandrite (lived 347/348–465/466), as well as two previous popes: Shenouda I (Papacy 859–880) and Shenouda II.

Following the death of Pope Cyril VI on 9 March 1971, the selection process resulted in Bishop Shenouda's becoming the new Pope. He was consecrated on 14 November 1971. During his papacy, the Coptic church grew significantly. He appointed the first bishops for North American dioceses, which now contain more than 250 parishes (214 in the United States, 38 in Canada and one in Mexico), up from four in 1971. He also appointed the first Coptic bishops in Europe, Australia and South America. Within Egypt, he struggled for the welfare of his people and the Church. Pope Shenouda III was known for his commitment to ecumenism and advocated inter-denominational Christian dialogue. He devoted his writings, teachings and actions to spreading and propagating guidelines for understanding, peace, dialogue and forgiveness.

At the time of his death, Pope Shenouda III was viewed as one of the Great Patriarchs of the ancient Church of Alexandria, a well-known church father and teacher, a chief defender of the faith, and a noted Egyptian leader of the 20th and 21st centuries. He was given the title ‘Teacher of Generations’ for his great talent at relaying complicated theological and other religious concepts in a simple, understandable and deeply spiritual manner.
