Tierra del Fuego is in the Patagonia Argentina!! my country!!
Tierra del Fuego is a 150 mile
long peninsula off the southern tip of South
America, separated from the mainland by the Strait
of Magellan.
It is divided into Chilean and
Argentinean halves, and its principle mountain
range, a west-east range known as the Cordillera
Darwin, stretches across both halves.
The Cordillera is the continuation of the Patagonian
Andes, and rises along the southern shore. The
range holds beautiful ice-packed and misty
mountains, with large glaciers pouring down into
the sea.

It's translated as "land of fire". Ferdinand Magellan was the first European to visit this land in 1520 as his expedition made its way around the globe. He named it 'Land of Fire" for the beach fires he observed the aborigines building as a means of keeping warm and for cooking.

I agree with the first answer. Infact, Tierra del Fuego is in Argentina and Chile. The province of Tierra del Fuego includes the eastern part of the archipelago of Tierra del Fuego, Falkland Islands (Islas Malvinas), South Georgia and the South Sandwich Islands (Islas Georgias del Sur y Sandwich del Sur), Argentine Antarctica. Its capital is Ushuaia. The Chilean Tierra del Fuego Province is a part of the Magallanes and Antartica Chilena Region. The capital of this province is Porvenir.
