Trinity Church, in Midtown Houston, Texas, is a parish church in the Episcopal Diocese of Texas. Trinity was founded in 1893 as a Mission from Christ Church in a part of Houston then called the "Fairground Addition", now known as Midtown. It is the second-oldest Episcopal parish in Houston. Trinity was, at one time, one of the largest parishes in the Episcopal Church. Such notables as Walter Cronkite and Denton Cooley have been members of the parish. Its membership declined sharply as its parishioners moved to the suburbs in the 1950s and 1960s. In the 2000s membership has grown steadily.
