Mark David Haverland (born Youngstown, Ohio, 1956) is an American Continuing Anglican bishop. He is the archbishop and metropolitan of the Anglican Catholic Church.
He studied at Kenyon College, taking his MA at Duquesne University and his Ph.D. at Duke University. His dissertation was about Anglican theologian Henry Hammond.
He was ordained a deacon in 1981 and a priest in 1982. He served in several Anglican Catholic parishes in Pennsylvania, North Carolina and Georgia, spending most of his priest career at St. Stephen's Parish, in Athens, Georgia.
Haverland was elected and consecrated Bishop Ordinary of the Diocese of the South in 2000, succeeding the deceased William Lewis. He would be elected and enthroned as archbishop and metropolitan of the Anglican Catholic Church at their 16th Provincial Synod, held in Grand Rapids, Michigan, to substitute the retired John Vockler in 2005. He has remained as bishop ordinary of the Diocese of the South.
He responded critically to Pope Benedict XVI's Anglicanorum Coetibus, in a document issued in January 2010, despite recognizing positives aspects in the provision.
He has collaborated in many publications, including Touchstone, The New Oxford Review and The Journal of Religion. He wrote Anglican Catholic Faith and Practise (2004).
