You might’ve seen the headlines or a weirdly labeled map lately and wondered if your geography teacher lied to you. Honestly, it sounds like one of those internet rumors that starts on a message board and just refuses to die. But if you’re asking did Trump actually rename the Gulf of Mexico, the answer is more "yes" than you probably think—at least according to the United States federal government.
It wasn't a joke.
On January 20, 2025, just hours after being sworn in for his second term, President Donald Trump signed Executive Order 14172. The title was a mouthful: "Restoring Names That Honor American Greatness." This wasn't just about small parks or post offices. The order explicitly directed federal agencies to stop using the term "Gulf of Mexico" and start using the "Gulf of America" for the U.S. continental shelf area.
The Day the Name Changed (For the Feds)
It happened fast.
One day you're looking at a standard NOAA weather chart, and the next, the Department of the Interior is issuing press releases about the "Gulf of America." By January 24, 2025, the Interior Department confirmed that all federal nomenclature was being updated. This wasn't a suggestion. It was a mandate for the executive branch.
The logic from the White House was pretty straightforward, if you follow the "America First" line of thinking. Trump argued during his inaugural address that the body of water is a "vital asset" to the U.S. economy, energy production, and national security. He basically said that since American taxpayers fund the Coast Guard that patrols it and the rigs that drill in it, the name should reflect the country.

But wait. There’s a catch.
An executive order is a powerful tool, but it has limits. It changes how the U.S. government talks. It doesn’t automatically change how the rest of the world—or even the guy down the street—talks.
Is it Legal or Just Symbolic?
You’ve got to look at the U.S. Board on Geographic Names (BGN). Usually, they’re the ones who handle this stuff with a lot of boring meetings and maps. But under Trump's order, they were basically told to bypass their usual protocols. Secretary of the Interior Doug Burgum signed a follow-up order on February 7, 2025, telling the BGN to get the Geographic Names Information System (GNIS) updated immediately.
If you go to a federal website today, you’ll see it. The Coast Guard even issued a "Final Rule" in March 2025 to update the Code of Federal Regulations. They literally went through thousands of pages of laws and swapped "Mexico" for "America."
The Google Maps Effect
This is where it gets real for most of us. We don't read the Federal Register for fun. We use our phones.

In February 2025, Google Maps did something interesting. They didn't just pick a side; they localized it. If you’re sitting in Dallas or Miami, your map likely says "Gulf of America." If you’re in Mexico City, it definitely still says "Golfo de México." If you're in London? You might see both.
This "border-aware" cartography isn't new—Google does the same thing with the Sea of Japan and the Persian Gulf—but it’s the first time we’ve seen it applied to such a massive body of water right on our doorstep.
The International Backlash
Mexico was not thrilled. Obviously.
President Claudia Sheinbaum didn't hold back. She even joked about renaming North America to "Mexican America" to show how ridiculous she thought the whole thing was. More seriously, her government pointed out that the name "Gulf of Mexico" is recognized by the United Nations and has been on maps since the 1500s.
It’s a bit of a diplomatic mess.

- The UN position: They still recognize the Gulf of Mexico.
- The UK: They’ve officially declined to change their maps, citing common usage.
- Airlines: Most international flight paths still use the original name for navigation to avoid confusion with foreign air traffic control.
The reality is that while the U.S. can call its "Third Coast" whatever it wants, the "Gulf of America" name stops being official about 12 nautical miles off the coast where international waters begin.
Why This Still Matters in 2026
We're now a year into this change, and the dust hasn't really settled. The "Gulf of America Day" (which Trump declared as February 9th) was a big deal in some Gulf Coast states but ignored in others.
Politics, as always, is the main driver. A poll by Marquette University in early 2025 showed that about 71% of Americans actually opposed the name change. People generally don't like having to buy new maps or re-learning what they knew in third grade.
However, for the "America First" crowd, it’s a massive symbolic win. It’s seen as reclaiming sovereignty. When you hear the White House Press Secretary refer to the "Gulf of America," it's a signal. It tells you exactly who is in charge and what their priorities are.
What You Should Actually Do
If you’re confused about what to call it, don't sweat it. Unless you're writing a federal grant or filing paperwork with the Coast Guard, nobody is going to arrest you for saying "Gulf of Mexico."
Here is the practical breakdown:
- Official Business: If you’re working with U.S. federal agencies (NOAA, Interior, Coast Guard), use "Gulf of America." It’ll make your life easier and keep your paperwork moving.
- Travel & Boating: Check your GPS. If you’re using a U.S.-sourced chart, it’s going to be "Gulf of America." Just make sure you know your coordinates; the water hasn't moved.
- General Conversation: Most people still say "Gulf of Mexico." It’s a 500-year-old habit. It’s going to take more than an executive order to change the way people talk at a beach bar in Destin.
Basically, the name changed on the paper, but the water stayed the same. It's a classic case of political branding meeting geographic reality. Whether "Gulf of America" sticks for the long haul or gets reversed by the next administration is anyone's guess, but for now, the U.S. government is sticking to its guns.
