Proclamation declaring Gulf of Mexico as 'Gulf of America'
On February 9, 2025, President Trump signed Proclamation 2025-02637 declaring the Gulf of Mexico shall be referred to as the 'Gulf of America.' The proclamation is a naming declaration with no direct operational impact on federal agencies, regulations, or resource management. The confirmed effect is that official U.S. government communications and documents will use this new designation, though international maritime law, treaties, and most global usage remain unchanged.
