The drinking age in St. Maarten is 18, and that applies on both the Dutch side (Sint Maarten) and the French side (Saint-Martin). The number is the same across the island, but the laws behind it, the penalties for breaking it, and how strictly things get enforced are not.
Dutch Side Rules
Sint Maarten, the southern portion of the island and a constituent country within the Kingdom of the Netherlands, sets the legal age for buying and consuming alcohol at 18. The rule covers beer, wine, and hard liquor equally, and it applies in bars, restaurants, nightclubs, and retail shops. The governing law is the Licensing National Ordinance, which regulates how businesses obtain and keep their permits to sell alcohol.1Government of Sint Maarten.

A business that sells alcohol to anyone under 18 risks losing its operating license. The obligation sits on the seller, not the buyer, so bartenders and cashiers can and do ask for identification before completing a sale. Enforcement is lighter at beach bars and casual open-air spots than at formal nightclubs, but the legal threshold is the same everywhere.
French Side Rules
The northern French side follows France’s national alcohol laws, which also set the minimum age at 18. Under Article L3342-1 of the Code de la santé publique, selling or giving alcohol to anyone under 18 is illegal in bars, shops, restaurants, and all other public places. The person selling the drink must ask for proof of age if there is any doubt.2Service-Public.fr. Drunkenness – Alcoholism
Penalties are steeper on the French side. A business caught selling alcohol to a minor faces a fine of up to €7,500, and the same penalty applies to giving away free drinks to minors in any public setting. Repeat offenses can lead to permanent loss of an establishment’s operating permit.2Service-Public.fr. Drunkenness – Alcoholism
Which Side’s Rules Apply to You
There is no passport control, no customs checkpoint, and no visible barrier between the Dutch and French territories. You can drive or walk across without stopping. What that means for alcohol enforcement: the rules that apply to you depend on the physical location of the bar or shop you are in, not which side of the island you arrived on. Step from a Dutch-side beach bar into a French-side bistro and the French penalties are now the ones in force.
What ID to Bring
Carry a physical, government-issued photo ID when you plan to drink. A passport is the most universally accepted document on both sides. A valid driver’s license works at most establishments, though some venues, particularly on the French side, may prefer a passport or national identity card.
Digital copies of your ID on a phone are not reliably accepted. Some bartenders and door staff will turn you away if you can’t produce a physical document, regardless of how old you look. If you’d rather not carry your passport everywhere, bring a clear photocopy along with your driver’s license as a backup, but acceptance of copies varies by venue.
Driving After Drinking
The relaxed drinking culture stops at the driver’s seat. Sint Maarten enforces a blood alcohol concentration limit of 0.05%, lower than the 0.08% most American visitors are used to. For a typical adult, one or two drinks can put you at or over the threshold.
The French side also uses 0.05% (0.5 g/L). Novice drivers on the French side face a stricter 0.02% limit, which effectively means zero drinks. Given how easy it is to cross between the two sides, a taxi or rideshare is the safer call after any amount of drinking. Penalties for drunk driving on either side can include fines, license suspension, and arrest.
