The Episcopal Church (TEC) is governed by a General Convention and consists of 96 dioceses in the United States proper, plus ten dioceses in other countries or outlying U.S. territories, the diocese of Convocation of Episcopal Churches in Europe, and a diocese for Armed Services and Federal Ministries, for a total of 108 dioceses.
A diocese, which is led by a bishop, includes all the parishes and missions within its borders, which usually correspond to a state or a portion of a state. Some dioceses includes portions of more than one state. For example, the Diocese of Washington includes the District of Columbia and part of Maryland.
