Antigua and Barbuda borders no countries by land. It’s an island nation, so the only neighbors it has are across open water.
That’s the short answer most people are after. But the more useful answer is the list of who’s actually nearby — because a country can be your closest neighbor across 40 miles of sea even if you’ll never drive there.
TLDR
- Land borders: zero. Antigua and Barbuda is a twin-island nation surrounded entirely by the Caribbean Sea and Atlantic Ocean.
- Maritime neighbors: Saint Kitts and Nevis, Montserrat, Guadeloupe, Anguilla, and Saint Barthélemy.
- Nearest sovereign country: Saint Kitts and Nevis, roughly 60 miles (about 95 km) west.
- Nearest land of any kind: Montserrat, a British Overseas Territory southwest of Antigua.
Why an island has “borders” at all
Here’s the part the quick reference pages skip. When people ask which countries border Antigua and Barbuda, they’re usually picturing a land border — a line on a map you can walk across, like the one between the US and Canada. By that definition, the answer is none. The nation sits alone in the Leeward Islands of the eastern Caribbean, with water on every side.
But countries also have maritime borders: the invisible lines where one nation’s territorial waters and exclusive economic zone meet another’s. The United Nations Convention on the Law of the Sea sets these at 12 nautical miles for territorial seas and up to 200 nautical miles for the exclusive economic zone. For an island packed into a cluster like the Leewards, those zones bump up against the neighbors fast. So Antigua and Barbuda shares sea boundaries even though it shares no soil. It’s part of a wider crowd, too: it sits among the twenty countries that border the Caribbean Sea, each with its own slice of that shared water.
That distinction is the whole answer. No land borders, several maritime ones.
The five maritime neighbors
Going roughly clockwise around the islands:
Saint Kitts and Nevis (west)
The nearest fully sovereign country. This two-island federation sits about 60 miles west of Antigua. If you’re answering a trivia question that asks for the closest country — not territory — this is the one. Both are independent members of the Commonwealth and the Organisation of Eastern Caribbean States, so they share a currency too: the Eastern Caribbean dollar. The relationship runs the other way as well, since Antigua and Barbuda is one of the closest neighbors that border Saint Kitts and Nevis.
Montserrat (southwest)
The closest land of any kind, around 30 miles southwest of Antigua. Montserrat is a British Overseas Territory, not an independent nation, which is why it doesn’t show up when the question is phrased strictly as “countries.” Its southern half has been off-limits since the Soufrière Hills volcano erupted in 1995, and Antigua became the main air gateway for people traveling to and from the island.
Guadeloupe (south)
A French overseas region sitting south of Antigua, past Montserrat. Because it’s part of France, it’s part of the European Union — the euro is the currency, and a French passport works there. It’s a territory in the political sense but legally a full region of France, not a separate country.
Anguilla and Saint Barthélemy (northwest)
Both lie to the northwest, near Saint Kitts and Nevis. Anguilla is another British Overseas Territory; Saint Barthélemy (St. Barts) is a French overseas collectivity. Neither is a sovereign state, but both share maritime boundaries with Antigua and Barbuda’s waters.
Distance and direction at a glance
| Neighbor | Direction | Approx. distance | Status |
|---|---|---|---|
| Montserrat | Southwest | ~30 mi (48 km) | British Overseas Territory |
| Saint Kitts and Nevis | West | ~60 mi (95 km) | Sovereign country |
| Guadeloupe | South | ~80 mi (130 km) | French overseas region |
| Saint Barthélemy | Northwest | ~95 mi (150 km) | French collectivity |
| Anguilla | Northwest | ~100 mi (160 km) | British Overseas Territory |
Distances are straight-line, island to island, and vary depending on which points you measure between. Treat them as a ranking rather than navigation figures.
Sovereign country vs. territory: who’s actually a “country”
This trips up nearly every list. Of the five neighbors, only Saint Kitts and Nevis is an independent country. The other four are governed from London or Paris:
- British: Montserrat, Anguilla
- French: Guadeloupe, Saint Barthélemy
So if a quiz, a homework question, or a customs form asks for the nearest country, the answer is Saint Kitts and Nevis. If it asks for the nearest land, it’s Montserrat. Getting those two confused is the single most common mistake in answers to this question.

Frequently asked questions
Does Antigua and Barbuda have any land borders? No. It’s an island nation with no shared land boundaries. Every neighbor is across open sea.
What is the closest country to Antigua and Barbuda? Saint Kitts and Nevis, about 60 miles to the west. It’s the nearest independent, sovereign country.
What is the nearest land to Antigua and Barbuda? Montserrat, roughly 30 miles southwest — but it’s a British Overseas Territory, not a separate country.
Are Antigua and Barbuda two separate countries? No. Antigua and Barbuda are two main islands (plus smaller ones) that together form a single sovereign nation, with the capital, St. John’s, on Antigua.
Is Antigua and Barbuda part of any larger country? No. It’s been fully independent since 1981. Before that it was a British colony, which is why English is the official language and it remains in the Commonwealth.

The bottom-line answer
Antigua and Barbuda borders no countries by land. Its sea neighbors, nearest first, are Montserrat, Saint Kitts and Nevis, Guadeloupe, Saint Barthélemy, and Anguilla — but only Saint Kitts and Nevis is a sovereign country. Remember that one distinction and you’ve got the right answer to whatever version of the question you’re facing.
