President-elect Donald Trump announced Tuesday his intention to rename the Gulf of Mexico as the “Gulf of America,” calling it a name with a “beautiful ring to it.”
The proposal marks Trump’s latest bid to reshape geopolitical boundaries, following past remarks about Canada as the “51st State,” Denmark ceding Greenland, and Panama returning the Panama Canal.
Since launching his first presidential campaign in 2016, Trump has frequently clashed with Mexico over border security, tariffs, and trade policies. During his tenure, his administration constructed or refurbished approximately 450 miles of wall along the U.S.-Mexico border.
The Gulf of Mexico, often called the United States’ “Third Coast,” stretches across five southeastern states. Mexicans refer to the body of water as “El Golfo de México.”
Renaming international bodies of water isn’t straightforward. The International Hydrographic Organization (IHO), which oversees the uniform naming of global seas, oceans, and waterways, requires broad consensus for changes.
While countries may use different names in domestic contexts, a unilateral change by the U.S. would not necessarily impact global usage. A similar precedent exists with the U.S. renaming Mount McKinley to Denali in 2015, which applied solely within national borders.
The Gulf of Mexico’s name has been documented for over four centuries, likely deriving from the Native American city of “Mexico.” Attempts to rename portions of the Gulf have arisen before. In 2012, a Mississippi legislator proposed renaming state waters as the “Gulf of America” but later called the suggestion a joke.
In 2010, comedian Stephen Colbert quipped that the Gulf should be renamed after the Deepwater Horizon oil spill, saying, “We broke it, we bought it.”
Trump’s announcement follows a history of global disputes over place names. For instance, South Korea contests Japan’s naming of the Sea of Japan, while Iran defends the “Persian Gulf” against alternative labels like the “Arabian Gulf.”
While Trump’s proposal may reignite debate over the Gulf of Mexico’s name, significant international consensus would be required for formal adoption on a global scale.
