Which island contains Ushuaia, often called the world’s southernmost city?

Tierra del Fuego is the island containing Ushuaia, often called the world’s southernmost city.

The island lies at the southern tip of South America and is separated from mainland Patagonia by the Strait of Magellan. Argentina and Chile share the island, with the international border running broadly from the Beagle Channel area toward the Atlantic coast.

Ushuaia is in Argentina’s Tierra del Fuego Province on the island’s southern coast. The city promotes itself as the southernmost city in the world, although the wording can vary depending on how “city” and “settlement” are defined.

Tierra del Fuego has mountains, glaciers, forests, and windswept steppe. Its name, meaning “Land of Fire,” was recorded by European navigators who saw Indigenous fires along the shores.
