Texas

Texas is the most populous state in the Southern United States. It borders Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, and an international border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south and southwest, that forms a natural boundary delineated by the Rio Grande. Texas has a coastline on the Gulf of Mexico to the southeast. Covering 268,596 square miles (695,660 km2) and with an estimated population of over 31.7 million residents in 2025, it is the second-largest U.S. state by area and population. Texas is nicknamed the "Lone Star State" for the single star on its flag, symbolic of its former status as an independent country, the Republic of Texas.
