So you're looking for St. Martin. You’ve probably stared at a map of the Caribbean until your eyes blurred, wondering how an island so famous can be so hard to spot. Honestly, it’s tiny. Most maps of the Western Hemisphere treat it like a literal speck of dust, often overshadowed by the "big guys" like Cuba or Puerto Rico.
But size isn't everything.
To find where is st martin on the map, you have to look at the northeastern curve of the Caribbean Sea. Specifically, it sits within the Leeward Islands, which are part of the Lesser Antilles. If you find Puerto Rico, move your finger about 190 miles (300 km) to the east. You’ll hit a little cluster of islands. That’s where the magic happens.
It’s a weird place, geographically speaking. You aren't just looking for one territory; you’re looking for a 34-square-mile rock that two different countries call home.
The Coordinates and the Neighbors
If you’re the type of person who needs the exact numbers, here they are: $18.06^\circ N, 63.05^\circ W$.
St. Martin is essentially the "cool kid" in a very prestigious neighborhood. Directly to the north, just a short ferry ride away, is Anguilla. To the southeast, you’ll find the glitzy St. Barths. If you look southwest, you might spot the volcanic peak of Saba or the quiet shores of St. Eustatius.
On a clear day, you can actually see these neighboring islands from the shore. It makes the whole area feel like a sprawling, aquatic backyard.
Where Is St Martin on the Map? The Dual-Nation Mystery
Here is what most people get wrong. They look for "St. Martin" and get confused when they see "Sint Maarten" on the same piece of land.
It’s the smallest landmass in the world shared by two sovereign nations.
The northern 60% of the island is Saint-Martin, an overseas collectivity of France. The southern 40% is Sint Maarten, a constituent country within the Kingdom of the Netherlands.
Why the Split?
Legend says a Frenchman and a Dutchman had a walking race around the island to decide the border. The Frenchman drank wine, the Dutchman drank gin (or jenever), and the Frenchman ended up covering more ground because the gin made the Dutchman sleepy—or so the story goes.
The reality is a bit more bureaucratic. The Treaty of Concordia was signed back in 1648, and remarkably, it still holds up today. There is no hard border. No "show me your passport" moments when you drive from the French bakeries of Marigot to the Dutch casinos of Philipsburg. You just pass a small sign, and suddenly the streetlights look a little different.
Mapping the Two Sides: What’s Actually There?
If you zoom in on a high-resolution map, you’ll see the island looks a bit like a crumpled piece of paper dropped in the blue. It’s hilly, rugged, and surprisingly diverse for something you can drive across in 45 minutes.

The French North (Saint-Martin)
This side feels like a sleepy village in the South of France that accidentally ended up in the tropics.
- The Capital: Marigot. It’s got that colonial charm, a fort (Fort Louis) overlooking the bay, and some of the best croissants this side of Paris.
- The Vibe: Relaxed. Secluded.
- The Food: Grand Case is widely considered the culinary capital of the Caribbean. You go here for fine dining, not for fast food.
The Dutch South (Sint Maarten)
The Dutch side is where the party is. It’s more developed, louder, and definitely more Americanized.
- The Capital: Philipsburg. This is where the massive cruise ships dock. Front Street is a gauntlet of duty-free jewelry shops and electronics.
- The Airport: Princess Juliana International (SXM). This is the famous one. If you’ve seen videos of planes flying five feet over people's heads at a beach, that’s Maho Beach right here.
- The Vibe: Bustling. High-energy. Casinos everywhere.
Getting There: Landmarks to Look For
If you’re trying to find it via a flight path, most international travelers land at Princess Juliana on the Dutch side.
There is a second, smaller airport on the French side called Grand Case-Espérance, but that’s mostly for regional hops from places like Guadeloupe or St. Barths.
One major geographic feature you can't miss on the map is the Simpson Bay Lagoon. It’s one of the largest inland lagoons in the West Indies. The border actually runs right through the middle of the water. It’s a graveyard for old boats and a playground for mega-yachts, depending on which way the wind is blowing.
Surprising Geographic Facts
- Highest Point: Pic Paradis. It’s 1,391 feet (424 meters) high. You can hike to the top for a view that literally shows you the entire island and four neighboring countries at once.
- No Rivers: Despite all the lush green hills, there isn't a single permanent river on the island.
- Salt of the Earth: Before tourism, the island was famous for its salt pans. The indigenous name for the island was Soualiga, which means "Land of Salt."
Why the Map Location Matters for Your Trip
Knowing where is st martin on the map isn't just about geography trivia. It dictates your entire vacation.
Because it’s so central in the Leeward Islands, it’s the ultimate "hub." You can stay on St. Martin but spend your days "country hopping."
- Anguilla: 20-minute ferry.
- Saba: 15-minute flight or a 90-minute ferry (brace yourself, that water gets choppy).
- St. Barths: 45-60 minute ferry or a terrifyingly fun 15-minute flight.
The island’s position also puts it right in the hurricane belt. Most locals start watching the weather maps very closely from June through November. The island was famously flattened by Hurricane Irma in 2017, and the geography still shows the scars—though the resilience of the people there is honestly more impressive than the landscape.
How to Find It Without a GPS
If you’re looking at a physical map, find the "hook" of the Antilles. Follow the chain of islands down from Florida, past the Bahamas, past the Virgin Islands. Just as the chain starts to curve south toward South America, you'll see a tiny cluster.
Look for the island shaped a bit like a triangle with a bite taken out of the bottom. That’s it.
Actionable Insight for Travelers:
If you're planning a visit, don't just book a hotel and stay put. Since the island is so small, rent a car. You can experience two different cultures, two different languages, and two different "countries" in a single afternoon. Just remember that while the Dutch side uses the Guilder (mostly USD), the French side is strictly Euro-centric, though they’ll usually take your dollars at a "one-to-one" rate if you're lucky.
Check your map for Orient Bay on the French side for the best beaches, and Simpson Bay on the Dutch side if you want to be walking distance to the best bars.
The island might be a speck on the globe, but once you're on the ground, it feels massive. One day you're eating escargot in a quiet cafe, and the next you're dodging the jet blast of a Boeing 747. Not bad for a 34-square-mile rock.
