The coastal states that have a shoreline on the Gulf of Mexico are Texas, Louisiana, Mississippi, Alabama, and Florida, and these are known as the Gulf States.

Yes, Texas has a significant coastline along the Gulf of Mexico, which is a large marginal sea of the Atlantic Ocean. The Texas Gulf Coast stretches for approximately 367 miles (591 km) if measuring the direct coastline, though the total shoreline—including bays, inlets, and islands—exceeds 3,300 miles according to NOAA. This coastal region borders Southeast Texas, the Coastal Bend, and South Texas. Major cities such as Galveston, Corpus Christi, and Brownsville are key coastal hubs. The coastline is characterized by a series of barrier islands, such as Padre Island (the longest barrier island in the world) and Galveston Island, which protect the mainland from storm surges. These coastal waters are vital for the state’s economy, supporting massive shipping ports (like the Port of Houston), a thriving commercial fishing industry, and popular tourism destinations known for their sandy beaches and warm sub-tropical climate.
