Patagonia is a region shared by which two South American countries?

Patagonia is a region shared by Chile and Argentina.

It occupies the southern part of South America, extending across the Andes and reaching both the Pacific and Atlantic sides of the continent. Argentina contains most of Patagonia’s land area, including broad eastern plateaus, deserts, and steppe. Chilean Patagonia is narrower and more fragmented, marked by fjords, islands, temperate rainforests, glaciers, and channels.

Patagonia is a geographic and cultural region, not a single country or unified administrative province. Its exact northern boundary varies by definition: the Colorado River is often used for Argentine Patagonia, while Chilean boundaries may be drawn near the Huincul Fault or farther south. Tierra del Fuego is commonly included in the region.

A frequent mistake is treating Patagonia as exclusively Argentine because many famous attractions—such as the Patagonian Desert—are there. Chile contributes equally distinctive landmarks, including Torres del Paine and much of the Southern Patagonian Ice Field.
