Ecclesiastical provinces and dioceses of the Episcopal Church

The Episcopal Church (TEC) is governed by a General Convention and consists of 99 dioceses in the United States proper, plus eleven dioceses in other countries or outlying U.S. territories and the diocese of Convocation of Episcopal Churches in Europe, for a total of 111 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.
