Maximos Sedfaoui (17 August 1863 – 27 February 1925) was the locum tenens and Apostolic Administrator (مدبّر رسولي) of the Coptic Catholic Church after the resignation of Patriarch Kyrillos Makarios in 1908. The Patriarch's exclusion and eventual travel to Beirut, Lebanon and the appointment of Sedfawi was greeted by a long series of opposition and demands for the reinstatement of Patriarch Makarios, but to no avail.
