List of countries and territories by number of land borders

This list gives the number of distinct land borders of each country or territory, as well as the neighbouring countries and territories. The length of each border is included, as is the total length of each country's or territory's borders.

Countries or territories that are connected only by man-made structures such as bridges, causeways or tunnels are not considered to have land borders. However, borders along lakes, rivers, and other internal waters are considered land borders for the purposes of this article.

Land borders

Distinct land neighbours: Refers to the number of unique countries a nation borders via land.
