Geography basics

Counting neighbours

A country's neighbours are the countries it shares a land border with. Sea borders don't count, so two countries facing each other across a strait are not neighbours.

Big countries in the middle of continents tend to have the most. Islands have none at all.

Counting neighbours

A country's neighbours are the countries it shares a land border with. Sea borders don't count, so two countries facing each other across a strait are not neighbours.

Big countries in the middle of continents tend to have the most. Islands have none at all.

Only one neighbour

Some countries have exactly one: Canada (the United States), Portugal (Spain), Ireland (the United Kingdom), Denmark (Germany), Haiti and the Dominican Republic, and the tiny ones inside Italy, San Marino and Vatican City.

Around 40 countries in MapGO's data have no land border at all, from Japan and Iceland to Australia and New Zealand.

Territories change the answer

France has 8 neighbours in Europe. Count French Guiana, an overseas part of France in South America, and Brazil and Suriname join the list.

In fact most measurements make France's longest land border the one with Brazil, just ahead of its border with Spain.
