The Gulf of America Act proposes to officially rename the Gulf of Mexico as the "Gulf of America" within the State of Alabama. The bill mandates that all state and local entities, as well as their employees, refer to this body of water as the "Gulf of America" starting October 1, 2026. It requires these entities to update all newly created maps, documents, educational materials, websites, and official communications to reflect this name change. Additionally, they are encouraged to make reasonable efforts to update pre-existing resources, although compliance is not required if it imposes an operational or financial burden.

The act also includes a provision that allows public K-12 schools and institutions of higher education to use the term "Gulf of Mexico" in academic contexts when appropriate for historical purposes. The bill will take effect on October 1, 2026, and it replaces all references to the Gulf of Mexico with the Gulf of America in Alabama's legal framework.
