Which country has the longest coastline in the world?
Hint: This country touches three oceans and has more coastline than any other nation combined!
Canada has the longest coastline in the world.
Canada has the longest coastline in the world, stretching approximately 243,042 kilometers (151,019 miles).
Bordered by three oceans—the Pacific, Atlantic, and Arctic—Canada’s vast shoreline is more extensive than the coastlines of the next several countries combined.
This immense length is due to Canada’s numerous bays, inlets, and islands, which add to its intricate coastal geography.
In comparison, the country with the second-longest coastline, Indonesia, has a significantly shorter shoreline of about 99,083 kilometers (61,567 miles). Canada's extensive coastline plays a crucial role in its climate, biodiversity, and maritime industries, solidifying its position as the country with the most expansive shorelines on Earth.
