Proposing a constitutional amendment regarding the terminology used in the Texas Constitution to refer to the partially landlocked body of water on the southeastern periphery of the North American continent.

SJR 63 is a procedural bill proposing a constitutional amendment to replace "Gulf of Mexico" with "Gulf of America" in multiple sections of the Texas Constitution. It specifically amends Articles I, VIII, IX, and XI to update terminology related to coastal beaches, tax relief for offshore equipment, county beach regulations, and coastal county tax authority. This change affects only constitutional language - no new policies or rights are created. The bill was reported adversely by the Senate Committee on State Affairs with a 8-0 vote on April 14, 2025, meaning it did not advance.
