The Gulf of Whatnow? Mapmakers grapple with Trump’s geographic renaming plans

What’s in a name change, after all?

The water bordered by the Southern United States, Mexico and Cuba will be critical to shipping lanes and vacationers whether it’s called the Gulf of Mexico, as it has been for four centuries, or the Gulf of America, as President Donald Trump ordered this week. North America’s highest mountain peak will still loom above Alaska whether it’s called Mt. Denali, as ordered by former President Barack Obama in 2015, or changed back to Mt. McKinley as Trump also decreed.

But Trump’s territorial assertions, in line with his “America First” worldview, sparked a round of rethinking by mapmakers and teachers, snark on social media and sarcasm by at least one other world leader. And though Florida Governor Ron DeSantis put the Trumpian “Gulf of America” on an official document and some other gulf-adjacent states were considering doing the same, it was not clear how many others would follow Trump’s lead.

Mexican President Claudia Sheinbaum joked that if Trump went ahead with the renaming, her country would rename North America “Mexican America.” On Tuesday, she toned it down: “For us and for the entire world it will continue to be called the Gulf of Mexico.”
