St. Martin's Episcopal Church, Episcopal church in Houston, Texas, United States

St. Martin's Episcopal Church is a Gothic Revival church at 717 Sage Road, completed on 11 April 2004 and designed by Jackson & Ryan Architects after St. Elizabeth's Church in Marburg, Germany. Its spires rise 188 feet above a seven-acre campus that also holds Founders' Hall (1954), Old Church (1959), a chapel, a library, the Wayside Chapel and the Cloister Garden.

St. Martin's was founded on 7 September 1952 by J. Thomas Bagby, and 125 people attended the first service at the Hollyfield family home on Post Oak Road. It became a self-supporting parish with 263 communicants in January 1953, and four acres on Sage Road were bought in 1954 for the first church building, now Founders' Hall. A second church, now Old Church, followed in 1959, and by the tenth anniversary in 1962 there were 2,791 baptized members.

The parish worships in both traditional and contemporary liturgical styles, in the evangelical Anglican and mainline Anglican tradition, with six Sunday services and three on Wednesdays. Its name comes from the oldest surviving church in the English-speaking world, St. Martin's in Canterbury, dedicated to St. Martin of Tours, whose harvest feast is celebrated in western Europe.

The campus lies at 717 Sage Road, just north of the Galleria, on seven acres; the main church, Founders' Hall, Old Church, chapel and Cloister Garden stand together and can be walked between on foot. The Hope & Healing Center, Scout Center and The Island youth center opened in 2011.

A 15th-century triptych altarpiece depicting the life of St. Martin was acquired in 2007 and is displayed in the church. The building also hosted the public viewings and funerals of Barbara Bush in April 2018 and George H. W. Bush in December 2018.
