Which States Border Texas? A Guide to the Lone Star State's Neighbors

Texas shares borders with four U.S. states and an international boundary with Mexico. To the north, east, and west, its neighbors are:

• New Mexico — to the west
• Oklahoma — to the north (including the Panhandle)
• Arkansas — to the northeast
• Louisiana — to the east

To the south, the Rio Grande forms the natural border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas. The Gulf of Mexico forms the southeastern coastline. This diverse geography—from desert borders to piney woods and coastal plains—makes Texas a unique crossroads of North American regions.
