List of countries that border only one other country

There are generally three arrangements by which a country would have a single land border: Territory leased or ceded by one country to another for perpetual use, but not in sovereignty, such as Guantanamo Bay Naval Base in Cuba, or memorials, such as the American Cemetery in France, do not constitute true territorial borders because the land occupied remains a formal part of the host country.

This list is based on the Correlates of War Direct Contiguity data set, with maritime causeways and bridges not being counted.

These may be considered artificial "persistent" borderpoints for land vehicles or pedestrians, but are not typically considered land borders given their need for continuous operation and maintenance, as well as their ease of volume control or closure by either state.

Two countries are islands and have no land borders, but maintain fixed borderpoints with other nations.

In most cases, an integral part of a larger country shares a border with another nation.
