Quick Answer
Canada has the longest coastline, stretching about 243,042 km.
The Full Story
Canada's coastline extends approximately 243,042 km — more than any other country and longer than the next six countries combined. This enormous length is due to Canada's countless islands in the Arctic Archipelago, its deeply indented Atlantic coast (Newfoundland, Labrador, the Maritimes), and the vast Pacific coast of British Columbia. Indonesia ranks second with about 54,716 km, followed by Greenland (if counted separately from Denmark) and Russia. Coastline measurement is famously tricky — the more detail measured, the longer it gets (the "coastline paradox").
Key Facts
1.Canada has over 52,000 islands, many in the Arctic.
