The Episcopal Diocese of Dallas is a diocese of the Episcopal Church (United States) 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 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 dioceses of Dallas is opposed to the ordination of gay clergy but has chosen to stay within the Episcopal Church.

[1] A vast majority of the Diocese of Fort Worth, on the other hand, voted to break away from the Episcopal Church in 2008.

At this convention, George R. Sumner, then principal of Wycliffe College, Toronto, was duly elected to be VII Episcopal Bishop of Dallas.
