Countries by Coastline 2026
- The Caspian Sea, Dead Sea, and the Sea of Galilee are landlocked and do not grant ocean access, so their shores are not considered coastlines. As such, the coastlines of Russia, Iran, Israel, Jordan, Azerbaijan, Kazakhstan, Palestine, and Turkmenistan may all be lower than expected at first glance.
- Because coastlines follow winding paths rather than straight lines, coastline lengths vary significantly depending upon the unit of measurement employed. For example, measuring in 10-mile increments results in a much different and more accurate coastline length than measuring in 100-mile increments (this is often referred to as the coastline paradox).
- Values shown below were compiled by the US CIA and may have utilized different units of measurement for different countries.
Coastline is defined as the boundary where land meets the water and is often known as shoreline or seashore. It is created by waves crashing onto the shore, eroding the land. Coastlines hold great economic, military, and cultural importance to a country.
The following is a list of the top ten countries with the longest coastlines in the world.
Top 10 Countries with the Longest Coastlines

A large part of the population of this country lives along the coastline, including the capital city of Oslo.
3. Indonesia - 54,716 Km/34,000 Miles
While Indonesia may not be large in terms of landmass, the large number of islands that make up the country qualify it to rank second on the list of the largest coastlines.
