Wait. Is it the Gulf of Mexico or the Gulf of America?
Honestly, if you’re looking at a map today, the answer depends entirely on who printed it and where you’re standing. For over 450 years, everyone just called it the Gulf of Mexico. It was simple. Then, 2025 happened, and geography became a political firestorm.
So, where is the Gulf of America? Basically, it’s the exact same body of water you’ve always known as the Gulf of Mexico, but with a brand-new federal name tag. It’s that massive, bowl-shaped basin tucked between the curve of the United States, the eastern coast of Mexico, and the island of Cuba.
If you’re standing on the white sands of Destin, Florida, or looking out over the oil rigs in Galveston, Texas, the U.S. government now officially says you’re looking at the Gulf of America. But if you hop on a flight to Cancun or Veracruz? Yeah, nobody there is calling it that.
The 2025 Rebrand: Why the Name Changed
It all started on January 20, 2025. President Donald Trump signed Executive Order 14172, titled "Restoring Names that Honor American Greatness."

The order didn’t just suggest a name change; it mandated that all U.S. federal agencies stop using "Gulf of Mexico" and start using "Gulf of America." By February 2025, the Geographic Names Information System (GNIS)—the official database for every hill, creek, and pond in the U.S.—had updated its records.
The logic from the White House was pretty straightforward, if controversial. They argued that because the U.S. has roughly 1,700 miles of coastline along the basin and controls massive underwater oil and gas reserves there, the name should reflect American influence. Critics, however, were quick to point out that Mexico actually has more coastline (about 2,243 km) and a 500-year historical claim to the name.
Where Exactly Does the "Gulf of America" Begin and End?
Geographically, nothing changed. No new islands popped up, and the water didn't get any bluer. But the legal boundaries are a bit of a mess.
- The U.S. Perspective: Under the executive order, federal agencies use the name for the entire basin, but specifically emphasize the U.S. continental shelf extending to the maritime borders with Mexico and Cuba.
- The Digital Reality: This is where it gets weird for travelers. If you open Google Maps in Houston, it says "Gulf of America." If your friend in Mexico City opens the same app, it says "Gulf of Mexico." If you're in London? You might see both names listed side-by-side.
- The International Stance: The International Hydrographic Organization (IHO), which is the global authority on maritime names, still recognizes it as the Gulf of Mexico. Most countries outside the U.S. have ignored the change entirely.

Back in the 1500s, Spanish explorers called it Seno Mexicano or the Gulf of New Spain. Eventually, mapmakers settled on the name of the Mexica people (the Aztecs).
Fast forward to 2010, and comedian Stephen Colbert actually joked about renaming it the "Gulf of America" so the U.S. would take more responsibility for cleaning up the Deepwater Horizon oil spill. He famously said, "We broke it, we bought it." It was a joke then. In 2025, it became law.
Why Does It Matter for Your Next Trip?
If you’re planning a vacation, don’t stress too much about the terminology. Whether you call it the Gulf of America or the Gulf of Mexico, the destination remains one of the most incredible ecosystems on the planet.

- The Emerald Coast: The Florida Panhandle (think Pensacola and Destin) has some of the clearest water and whitest sand in the world.
- The Mississippi Delta: A massive, muddy, life-giving engine that feeds the entire Gulf.
- Texas Barrier Islands: Padre Island is the longest barrier island in the world and a massive spot for kiteboarding and bird watching.
The Real-World Impact
While the name change is a big deal in Washington D.C., it’s created a bit of a headache for scientists and sailors. Most academic journals still use the traditional name because they have to reference decades of existing research.
Similarly, the Associated Press (AP) initially refused to use the new name, leading to a temporary ban of their reporters from the Oval Office until a federal judge stepped in. It’s a strange time to be a cartographer, for sure.
Navigating the Name Change: Actionable Insights
If you’re traveling or doing business in the region, here’s how to handle the "Gulf of America" vs. "Gulf of Mexico" situation:
- Federal Paperwork: If you are filing U.S. government documents, permits, or contracts, use Gulf of America. Using the old name could lead to delays or administrative rejection in 2026.
- International Travel: When you’re in Mexico or Cuba, stick to Gulf of Mexico (or Golfo de México). Using the U.S. name locally is often seen as a political statement and might get you some side-eye.
- Digital Navigation: Be aware that your GPS or mapping app might toggle names depending on your settings or VPN. Don't be surprised if the label shifts as you cross the maritime border.
- Check Your Sources: If you're researching fishing regulations or environmental data, check the date of the publication. Post-2025 U.S. data will use the new name, while older data—and anything from international groups like NOAA’s global partners—will use the traditional name.
Geography usually moves at the speed of shifting tectonic plates. This time, it moved at the speed of a pen stroke. Whether the name "Gulf of America" sticks for the long haul or ends up as a historical footnote remains to be seen. For now, just remember: different name, same beautiful water.
