Central Texas

Central Texas is a region in the U.S. state of Texas roughly bordered on the West by San Saba to the Southeast by Bryan and the South by San Marcos to the North by Hillsboro. Central Texas overlaps with and includes part of the Texas Hill Country and corresponds to a physiographic section designation within the Edwards Plateau, in a geographic context.

Central Texas includes the Killeen-Temple-Fort Hood, Bryan–College Station, Waco metropolitan areas and Austin–Round Rock (also part of the Capital region). The Austin–Round Rock and Killeen-Temple-Fort Hood areas are among the fastest-growing metropolitan areas in the state. In the South, the Greater Austin and Greater San Antonio areas are separated from each other by approximately 80. mi along Interstate 35. It is anticipated that both regions may form a new metroplex similar to Dallas and Fort Worth. Some of the largest cities in the region are Austin, College Station, Killeen, Round Rock, and Waco. The largest U.S. Army installation in the country, Fort Cavazos (formerly Fort Hood), is located near Killeen.
