Tierra del Fuego is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan. The archipelago consists of the main island, Isla Grande de Tierra del Fuego, with an area of 48,100 km2 (18,572 sq mi), and a group of many islands, including Cape Horn and Diego Ramírez Islands. Tierra del Fuego is divided between Chile and Argentina, with the latter controlling the eastern half of the main island and the former the western half plus the islands south of Beagle Channel. The southernmost extent of the archipelago is at about latitude 55°S.
Tierra del Fuego is the southernmost, smallest, and least populous Argentine province.
Isla Grande de Tierra del Fuego also formerly Isla de Xátiva is an island near the southern tip of South America from which it is separated by the Strait of Magellan.

Southernmost settlements are cities, towns, weather stations or permanent military bases which are farther south than latitude 45°S. They are closely related to the Southern Ocean or either the Roaring Forties or Furious Fifties. Antarctic bases are excluded due to not having a permanent population.
Puerto Williams is the city, port and naval base on Navarino Island in Chile. It faces the Beagle Channel. It is the capital of the Chilean Antarctic Province, one of four provinces in the Magellan and Chilean Antarctica Region, and administers the communes of Chilean Antarctic Territory and Cabo de Hornos. It has a population of 2,874, including both naval personnel and civilians. Puerto Williams claims the title of world's southernmost city. The settlement was founded in 1953, and was first named Puerto Luisa. The town was later named after John Williams Wilson, a British man who founded Fuerte Bulnes, the first settlement in the Strait of Magellan since 1587. It has served primarily as a naval base for Chile. The Chilean Navy runs the Guardiamarina Zañartu Airport and hospital, as well as nearby meteorological stations. Since the late 20th century, the number of navy personnel has decreased in Puerto Williams and the civilian population has increased. In that period, tourism and support of scientific research have contributed to an increase in economic activity.
