St. Peter's Episcopal Church is located in McKinney, Texas, approximately 30 miles north of Dallas.
The church was designated a mission church in 1876, when services were held in private homes and offices. In 1890 the mission was elevated to the status of a parish, and in 1893 the original frame church was completed, on the site of the present church. A new sanctuary was built in 1926. In 1947, the church's women's guild sold mail order fruitcakes that raised money for the church.
In 1960 a fire destroyed the sanctuary and other valuables, and the current church building was built the next year, and extended in 1997.
The interim Rector is the Rev. Kathy Heitmann.
