You’re standing on a white sand beach in Destin or sipping a coffee in Veracruz, looking out at that massive, turquoise expanse of water. To you, it’s the Gulf. To mapmakers, it’s the Gulf of Mexico. But have you ever wondered what would happen if someone decided that name just didn't fit anymore? Maybe a politician wants to score points, or a massive cultural shift demands a new identifier. The question of who can change the name of the Gulf of Mexico isn't just a matter of printing new maps. It is a bureaucratic nightmare involving international law, domestic agencies, and the stubborn weight of history.
Names feel permanent. They aren't. We’ve seen Turkey become Türkiye and Bombay become Mumbai. But those are landmasses within a single border. A body of water shared by three different nations—the United States, Mexico, and Cuba—is a whole different beast. Honestly, it’s one of the most stable geographic labels on the planet, and there’s a reason for that.
The Domestic Gatekeepers: The U.S. Board on Geographic Names
If you are a citizen of the United States and you want to rename the Gulf, your first stop isn't the White House. It’s a relatively obscure group called the U.S. Board on Geographic Names (BGN). Established in 1890, this body was created because, back in the day, explorers and surveyors were naming the same mountains and rivers five different things. It was chaos.
The BGN has the final say on what the federal government calls any geographic feature. If the BGN doesn't sign off, the name doesn't exist on official U.S. maps, period. They are notoriously conservative about changes. They hate "commemorative" naming—naming things after people—unless that person has been dead for at least five years. But more importantly, they prioritize "local usage." If everyone in the region calls it the Gulf of Mexico, the BGN sees no reason to stir the pot.
To get them to move, you’d need to prove that the current name is derogatory or that there is a massive, overwhelming public consensus for a change. Even then, the BGN only controls U.S. federal usage. They can't tell the rest of the world what to do. Basically, the BGN could decide to call it the "Blue Circle," but if the rest of the world ignores them, the U.S. just looks silly.
The International Hurdle: The IHO and GEBCO
This is where things get truly complicated. The Gulf of Mexico is international water. Because of that, the real authority is the International Hydrographic Organization (IHO), based in Monaco. They publish a document called Limits of Oceans and Seas (S-23). This is essentially the world’s "source of truth" for water names.

The IHO doesn't just take suggestions from random people. Changes usually come from member states. If the U.S. wanted a change, they’d have to coordinate with Mexico and Cuba. Can you imagine the diplomatic heavy lifting required for that? Mexico, quite understandably, would likely find any attempt to remove "Mexico" from the name of the Gulf to be a massive diplomatic insult. It’s their namesake. They have a historical claim to the nomenclature dating back to the Spanish colonial era when it was the Seno Mexicano.
Then there is GEBCO (General Bathymetric Chart of the Oceans). They work under the IHO and the Intergovernmental Oceanographic Commission of UNESCO. They handle the naming of sub-sea features—trenches, ridges, and basins. While they focus more on what’s under the water, their naming conventions follow the same rigid international protocols. To change a name at this level, you need consensus. In a world of polarized geopolitics, getting three nations and an international body to agree on a name change for a 600,000-square-mile body of water is practically impossible.
Why History Usually Wins
We have to look at "cartographic sovereignty." Most people think names are just labels, but they are actually claims of influence. During the early 16th century, the Gulf was often referred to as the "Gulf of New Spain." As Mexico gained independence and defined itself as a nation, the name "Gulf of Mexico" became the standard.
History is a heavy anchor.
Look at the "Sea of Japan" vs. "East Sea" dispute. South Korea has spent decades and millions of dollars trying to get the international community to use "East Sea" or at least a dual name. They’ve had some success with textbook publishers, but the IHO has largely stuck to "Sea of Japan" for the sake of "maritime safety." That’s the big secret: Safety.

Mariners use charts. If a name changes suddenly, and a distress call goes out using a new name that half the world’s coast guards don't recognize, people die. The IHO and national mapping agencies prioritize clarity over political correctness or branding every single time.
The Role of the President and Congress
Could the President of the United States change it? Sorta. But not really.
An Executive Order could theoretically instruct federal agencies to use a different name. We saw this in 2015 when President Obama officially changed the name of North America’s highest peak from Mount McKinley to Denali. However, Denali was already the name used by Alaskans. It was a restoration, not an invention.
If a President tried to rename the Gulf of Mexico to, say, the "American Gulf," they would face immediate legal challenges and international backlash. Congress could also pass legislation, but again, that law would stop at the shoreline. The moment a ship enters the Exclusive Economic Zone (EEZ) of Mexico, U.S. law regarding the name of the water becomes irrelevant.
What About Commercial Influence?
You might think big corporations or "Big Map" (Google, Apple, Garmin) have power here. They don't. While Google Maps is what most of us use to navigate to a taco stand, Google follows the lead of the BGN and international bodies. They don't want the liability of being the only map on Earth using an "unofficial" name.

There have been instances where digital maps show different names depending on which country you are viewing them from (this happens a lot in disputed territories in the Middle East or the South China Sea). But for a stable, non-disputed body of water like the Gulf, there is zero incentive for a tech company to go rogue.
The Verdict on Who Can Change the Name
The answer is: Everyone and No One.
Technically, the U.S. Board on Geographic Names can change it for U.S. maps. The IHO can change it for world charts. The Mexican government could call it whatever they want in their own textbooks. But for a name to actually change in the minds of 8 billion people and on every nautical chart from Tokyo to London, you would need:
- A massive geopolitical shift (like the total collapse or merger of the surrounding nations).
- Unanimous diplomatic agreement between the U.S., Mexico, and Cuba.
- Formal adoption by the IHO.
- Decades of "re-education" to phase out the old term.
It is one of the most difficult "brand" changes imaginable.
Actionable Insights for the Curious
If you’re interested in the power of naming or want to see how these disputes play out in real-time, here is how you can actually engage with this world:
- Monitor the BGN Quarterly Meetings: The U.S. Board on Geographic Names holds public meetings and publishes "Action Lists." You can actually see which local ponds, hills, and creeks are currently being renamed and why. It’s a fascinating look at how language evolves on the map.
- Explore GEBCO’s Undersea Feature Names: If you want to "name" something, you’re better off looking down. There are still many unnamed features on the ocean floor. While you can’t name the Gulf, scientists often propose names for newly discovered seamounts.
- Study the "S-23" Document: If you are a geography nerd, look up the IHO’s Limits of Oceans and Seas. It defines exactly where the Gulf ends and the Caribbean begins. It’s the "bible" of maritime borders.
- Respect Local Context: If you’re traveling, understand that names have deep roots. Calling it the "Gulf of Mexico" is more than a geographic necessity; it’s a nod to the shared history of the Americas.
The name isn't going anywhere anytime soon. It has survived wars, revolutions, and the rise of the internet. It turns out that some things are just too big to rename.
