Texas Triangle

The Texas Triangle is a region of Texas that contains the state's five largest cities and is home to over half of the state's population. The Texas Triangle is formed by the state's four main urban centers, Austin, Dallas-Fort Worth, Houston, and San Antonio, connected by Interstate 45, Interstate 10, and Interstate 35.

In 2004, the Texas Triangle contained five of the 20 largest cities in the U.S. and was home to over 70% of all Texans, with a population of 13.8 million. In 2025, its population reached nearly 23 million, following rapid growth across much of Texas.
