Mark Joseph Lawrence (born March 19, 1950, in Bakersfield, California) is an American Anglican bishop.  He has been the bishop of the Episcopal Diocese of South Carolina since 2008.  In November 2012, the diocese under his leadership withdrew from the national Episcopal Church to become an independent Anglican diocese and eventually came under the oversight of the Anglican Global South.  The national Episcopal Church does not recognize this diocesan withdrawal.  Instead, national leaders of the Episcopal Church consider Lawrence to have abandoned the Episcopal Church and his position as diocesan bishop.  According to the official website of the global Anglican Communion, the independent diocese under Lawrence's leadership is not a member of the communion.  However, the Steering Committee of Anglican primates of the Global South recognized Lawrence as bishop over a diocese "within the Anglican Communion" in December 2012 and recognized the diocese as part of the Global South in August 2014.  The status of the Diocese of South Carolina is currently the subject of state and federal lawsuits, but is settled in terms of canon law.  [Some debate this, as ACNA canon law does not apply to assets belonging to The Episcopal Church.]  Lawrence and other bishops in the Diocese are now formally affiliated with the Anglican Church in North America upon the unanimous admittance of the Diocese of South Carolina on 27 June 2017.
