The world’s geography is full of fascinating extremes, from the highest mountains to the deepest oceans. One of the most intriguing extremes is the southernmost city in the world, a place where civilization meets the wild, icy landscapes of the Southern Hemisphere.
Many people assume Antarctica hosts the southernmost city, but there are no permanent cities on the frozen continent. Instead, the world’s southernmost settlements are found in South America, particularly in Argentina and Chile.
In this topic, we’ll explore the southernmost city in the world, its climate, culture, and what makes it a unique place to visit or live.
What Is the Southernmost City in the World?
Puerto Williams – The Last City Before Antarctica
The official southernmost city in the world is Puerto Williams, a small but significant settlement located on Navarino Island in Chile. Situated on the southern tip of South America, Puerto Williams lies on the banks of the Beagle Channel, beyond Ushuaia, Argentina.

Puerto Williams is a remote, cold, and quiet town, but it holds the title of the southernmost city because of its permanent civilian population and municipal governance.
Why Is Puerto Williams Considered the Southernmost City?
To be classified as a city, a settlement must have a permanent population, government administration, and essential services. Puerto Williams, although small, meets these criteria.
Some places, like Villa Las Estrellas in Antarctica, are further south but are not considered cities because they are only research bases with rotating populations.
Puerto Williams also surpasses Ushuaia, Argentina, which is larger and more well-known but lies slightly farther north.
