Yes, you can absolutely use US Dollars (USD) throughout the entire island of St. Maarten (Dutch side) and St. Martin (French side). In the Dutch territory (Sint Maarten), the official currency is the Caribbean Guilder (XCG)—which recently replaced the Netherlands Antillean Guilder—but the US Dollar is accepted everywhere and is often the preferred currency for real estate and high-end retail. On the French side (Saint-Martin), the official currency is the Euro (EUR), but even there, USD is widely accepted in restaurants and shops. Most businesses list prices in both the local currency and USD. However, be mindful that if you pay in USD on the French side, you might receive change in Euros, and exchange rates at small vendors may not be as favorable as the official bank rate. For 2026 travelers, carrying smaller denominations of USD is the most convenient way to navigate the island without the need for frequent currency exchange.
