Ecclesiastical provinces and dioceses of the Episcopal Church
The Episcopal Church (TEC) is governed by a General Convention and consists of 108 dioceses: 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.
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.
