Texas's 10th congressional district of the United States House of Representatives stretches from the northwestern portion of the Greater Houston region to the Greater Austin region. It includes Houston suburbs such as Katy, Cypress, Tomball, and Prairie View, cities in east-central Texas including Brenham and Columbus, and northern Austin and some suburbs including Pflugerville, Bastrop, Manor, and Elgin. The current representative is Michael McCaul.
For most of the time from 1903 to 2005, the 10th was centered on Austin. It originally included large portions of the Texas Hill Country. Future President Lyndon B. Johnson represented this district from 1937 to 1949. During the second half of the 20th century, Austin's dramatic growth resulted in the district becoming more compact over the years. By the 1990s, it was reduced to little more than Austin itself and surrounding suburbs in Travis County.
