The drinking age in the Caribbean is 18 in most countries and territories, 16 in a handful of smaller nations, and 21 on nearly every cruise ship sailing from a U.S. port. Puerto Rico and the U.S. Virgin Islands both set the age at 18, which trips up a lot of American travelers who assume U.S. territories follow the mainland rule.
Islands Where the Age Is 18
Most of the region’s popular destinations require you to be at least 18 to buy or drink alcohol:
- The Bahamas (no alcohol sales on Sundays)
- Jamaica, under the Spirit Licence Act
- Dominican Republic, under its child protection code
- Barbados, under the Liquor Licences Act of 20211Barbados Parliament. Liquor Licences Bill, 2021
- Trinidad and Tobago, though the government has proposed raising it to 21
- Antigua and Barbuda, raised from 16 by a 2015 amendment
- Aruba and Curaçao
- Cayman Islands2Visit Cayman Islands. Common FAQs

- Sint Maarten and Saint-Martin (both sides of the island)
- Martinique and Guadeloupe, following French law
- Suriname
- Belize
Islands Where the Age Is 16
Several smaller nations still allow purchase at 16:
- Dominica, under its Liquor Licences Act
- Cuba
- Grenada, for on-premise sales under the Liquor Dealers’ Licenses Act
- Saint Kitts and Nevis
- Saint Lucia, where the Liquor Licence Act prohibits serving anyone “apparently under the age of 16”5Attorney General Chambers of Saint Lucia. Liquor Licence Act – Section 37
- Saint Vincent and the Grenadines
Haiti has no enacted minimum drinking age. A bill to set it at 18 passed the Haitian Senate in 2012 but was never formally enacted.
Puerto Rico and the U.S. Virgin Islands
Both U.S. territories set the drinking age at 18, not 21. Puerto Rico’s liquor statute prohibits sales only to persons under 18 and requires ID checks for anyone who appears younger than 27.6Justia Law. Puerto Rico Code Title 13 – Prohibition on the Sale or Donation of Alcoholic Beverages The U.S. Virgin Islands Code likewise makes it a violation to sell alcohol or tobacco to anyone under 18.7Department of Licensing and Consumer Affairs.

The federal law that pushed all 50 states to 21 works by withholding a share of federal highway funding rather than by setting an age directly.8Office of the Law Revision Counsel. United States Code Title 23 Section 158 – National Minimum Drinking Age Puerto Rico and the USVI kept their age at 18 and absorbed the funding penalty instead.
Drinking Age on Cruise Ships
On a cruise, the ship’s policy governs, not the flag of the island outside your porthole. Most major carriers sailing from U.S. ports enforce 21 for the entire voyage. Royal Caribbean states that the minimum age for alcohol on sailings originating from North America or the Caribbean is 21.9Royal Caribbean International. What is the Legal Drinking Age on Cruises Carnival applies the same rule across its sailings.
A few lines are more flexible. Oceania Cruises sets its general minimum at 21 but lets guests aged 18 to 20 buy beer and wine once the ship leaves U.S. territorial waters on Caribbean sailings.10Oceania Cruises. What is the Minimum Drinking Age Onboard Check your own line before you board; policies vary and sometimes shift by itinerary.
The idea that ships lower their onboard drinking age to match the local law at each port is mostly a myth for the big carriers. Neither Royal Caribbean nor Carnival adjusts its policy when docked. Cruise-line private islands stay stricter still: Royal Caribbean says the drinking age at its private destinations remains 21 regardless of where the sailing began.9Royal Caribbean International. What is the Legal Drinking Age on Cruises Step off the ship onto an independent island and local law applies; the ship itself is still the cruise line’s turf.
What ID to Carry
A passport is the safest ID across the region. It works everywhere, avoids questions about unfamiliar foreign license formats, and doubles as your travel document. Some bars accept a driver’s license, but a U.S. state license may not be recognized quickly by a bartender in Martinique.
Enforcement varies by setting. Large resorts and international hotels tend to card consistently because of licensing scrutiny and corporate liability. A beach shack or street vendor may never ask. If you look young, expect to be carded even well above the legal threshold. Puerto Rico’s rule that sellers request ID from anyone appearing under 27 is a good example of how wide those buffers can be.6Justia Law. Puerto Rico Code Title 13 – Prohibition on the Sale or Donation of Alcoholic Beverages
Drinking in Public
Legal age is only half of it. Rules on open containers and public drinking vary widely. French territories like Guadeloupe and Martinique allow local mayors to impose public drinking bans during peak seasons or holiday weekends, so carrying an open drink on certain streets or beaches after dark can be illegal even when the bar behind you is serving normally. Several other islands have similar municipal restrictions in tourist zones or near schools and churches.
A safe default is to drink where you bought it or take it back to your hotel. Walking between bars with an open drink is tolerated in some Caribbean towns and will get you stopped in others.
Drinking and Driving
This is where the loose-feeling atmosphere gets genuinely risky. Antigua and Barbuda, Barbados, Grenada, and Saint Vincent and the Grenadines have no statutory blood alcohol limit for drivers. Drunk driving is not legal there; police arrest impaired drivers under general traffic statutes. But without a defined BAC threshold, enforcement is subjective and outcomes are hard to predict.
Islands that do set a BAC limit generally use 0.05% to 0.08%. Penalties range from steep fines to vehicle impoundment to jail time. A DUI arrest as a foreign tourist can mean a night or more in a local jail before you see a magistrate, and you will likely need to hire a local attorney before you can leave the island. If you’re renting a car or a scooter, the practical rule is not to drink beforehand at all, especially given unfamiliar roads and left-hand driving on many islands.
Parents, Minors, and Private Homes
Many Caribbean nations draw a line between commercial sales and what happens inside a private home. Liquor laws regulate licensed establishments; a parent sharing wine with their teenager at a family dinner may face no legal restriction, even though that same teenager could not order a drink at a restaurant.
That exception does not carry into commercial settings. A parent sitting next to their 16-year-old at a restaurant in Barbados cannot order a beer for the minor. The restaurant’s license prohibits serving anyone under the legal age regardless of who else is at the table, and most venues will refuse even when a parent insists. Providing alcohol to someone else’s minor child is treated as a serious offense in most Caribbean jurisdictions, even in private settings; the family exception is narrow and applies to your own children.
