Episcopal Diocese of Dallas

The Episcopal Diocese of Dallas is a diocese of the Episcopal Church USA which was formed on December 20, 1895, when the Missionary District of Northern Texas was granted diocesan status at the denomination's General Convention the preceding October. The Rt Revd Alexander Charles Garrett, who had served as the first bishop of the Missionary District of Northern Texas, remained as bishop of the new diocese. The diocese began with thirteen parishes.

The Missionary District of Northern Texas was formed when a portion of the Episcopal Diocese of Texas was divided on February 2, 1875. Bishop Garrett named the oldest church in the district, which was Saint Matthew’s Episcopal Church, as his cathedral church and Dallas as his see. Saint Matthew's has remained the cathedral church of the bishop since that time. Bishop Garrett served until 1924.

There are more than seventy parishes and schools in the diocese. The diocese is involved in many national and international missionary outreach programs. The principal offices of the diocese are at the Diocesan House, which is, along with the cathedral church, located on the former site of Saint Mary's Episcopal College for Women. The diocese divided in 1983; the Episcopal Diocese of Fort Worth was formed from the division.
