What is the northernmost capital city of a sovereign country? Reykjavík, Iceland. At about 64°08′ north, Reykjavík is the highest-latitude capital of an independent sovereign state.

Reykjavík sits on Iceland’s southwest coast, where the North Atlantic Ocean helps moderate its climate despite its far-northern location. Iceland became a sovereign kingdom in 1918 and a republic in 1944, making Reykjavík the capital of a fully independent country.

The most common mix-up is Nuuk, Greenland, which lies slightly farther north at roughly 64°10′ north. Greenland, however, is an autonomous constituent country within the Kingdom of Denmark rather than a sovereign state. If constituent countries or territories are included, the answer changes.

Reykjavík’s latitude also produces dramatic seasonal daylight: around midsummer, darkness is brief, while winter days are very short. The name Reykjavík means “Smoky Bay,” referring to steam from nearby geothermal areas.
