Patagonia
Geographical region in southern South America spanning Argentina and Chile.
Patagonia is a region in southern South America that stretches across parts of both Argentina and Chile. It covers the southern section of the Andes, with lakes, fjords, temperate rainforests, and glaciers in the west, while the east is made up of deserts, tablelands, and steppes. The Pacific Ocean borders it to the west, the Atlantic Ocean to the east, and waterways like the Strait of Magellan, the Beagle Channel, and the Drake Passage lie to the south.
The region’s northern boundary isn’t fixed. In Argentina, the Colorado and Barrancas rivers—flowing from the Andes to the Atlantic—are often taken as the northern limit, which would include the provinces of Neuquén, Río Negro, Chubut, and Santa Cruz, plus the Patagones Partido in southern Buenos Aires Province. For Chilean Patagonia, most geographers and historians place the northern edge at the Huincul Fault in the Araucanía Region, extending through the Los Lagos, Magallanes, and Aysén regions. The Tierra del Fuego archipelago is sometimes included as part of Patagonia.
When Spanish explorers first arrived, various indigenous groups lived there. In a small northwestern part, some communities practiced limited farming, but most people were hunter-gatherers—traveling on foot across the eastern plains and using dugout canoes or dalcas in the western fjords and channels. After the horse was reintroduced, indigenous groups in northeastern Patagonia adopted a horseback-based nomadic lifestyle during the colonial period.
Spanish explorers launched expeditions and set up settlements, while the Spanish Crown focused on keeping rival European powers out of the area for strategic reasons. After independence, both Chile and Argentina claimed the southern territories and began colonizing their Patagonian regions throughout the 19th and early 20th centuries. This expansion caused a steep drop in indigenous populations, as their societies were disrupted by settlers from Argentina, the Chiloé Archipelago, mainland Chile, and Europe. Indigenous resistance was eventually crushed by military campaigns from both Argentina and Chile.
Today, Argentine Patagonia’s economy relies heavily on sheep farming and oil and gas extraction, while Chilean Patagonia’s economy centers on fishing, salmon aquaculture, and tourism.
The name Patagonia comes from the word *patagón*. Magellan used it in 1520 to describe the native tribes his expedition encountered, whom they thought were giants. These people, now believed to be the Tehuelche, were often taller than Europeans of the time. Argentine researcher Miguel Doura suggested the name might come from the ancient Greek region of Paphlagonia (in modern Turkey), possibly the home of a character in the chivalric romance *Primaleon* printed in 1512—ten years before Magellan reached the area. This idea was published in a 2011 report in the *New Review of Spanish Philology*.
Several place names in the Chiloé Archipelago have Chono origins, even though the main indigenous language there when the Spanish arrived was Mapudungun. Chronicler José Pérez García theorized that the Cuncos (also called Veliches) settled on Chiloé Island in pre-Hispanic times, pushed south by more northern Huilliches, who were themselves displaced by Mapuches. Though outside traditional Huilliche territory, the western Patagonian volcanoes Michimahuida, Hornopirén, and Chaitén have Huilliche etymologies.
In Chubut Province, the name comes from the word *chupat*, from a transitional language between southern and northern Tehuelche groups called Tewsün or Teushen. It means “transparency,” referring to the clarity and purity of the river that runs through the province. The Welsh pronunciation of *chupat* later became “Chubut,” and in Patagonian Welsh it is called “Camwy.” All three—Chupat, Chubut, and Camwy—mean the same thing and refer to the river and province. Welsh settlers and place names are linked to one of Wales’ projects, Project Hiraeth.
Because of their language, culture, and location, many Patagonians do not see themselves as Latinos and proudly call themselves Patagonians instead. People from Y Wladfa, Laurie Island, the Atlantic Islands, Antarctica (including the Chilean town “The Stars Village” and the Argentine civilian settlement “Hope Base”), and other non-Latin-speaking areas use this term as a patriotic and inclusive demonym. A Patagonian is someone who belongs to the region’s land, language, and culture—whether a citizen of Chilean or Argentine Patagonia, or a member of native communities that existed before the Boundary Treaty of 1881 divided the territory.
Patagonia is split into Western Patagonia (Chile) and Eastern Patagonia (Argentina), and several territories remain disputed, with groups claiming their rights. Mapuche people, who came from the Chilean Andes, voted to stay on different sides of Patagonia. Welsh settlers, who arrived from Wales and North America, voted to remain in Patagonia; when the treaty was signed, they chose to keep their settlement, language, schools, traditions, regional dates, flag, anthems, and celebrations separate from the country. Patagonians also live abroad in settlements.

Lore & Background
When Spanish explorers first arrived, Patagonia was inhabited by several indigenous groups. In a small portion of northwestern Patagonia, some communities practiced limited agriculture, while in the remaining territory most peoples lived as hunter-gatherers—travelling on foot in the eastern plains and using dugout canoes and dalcas in the western fjords and channels. During the colonial period, the indigenous groups of northeastern Patagonia adopted a horseback-based nomadic lifestyle following the reintroduction of the horse. Spanish explorers undertook several expeditions and established settlements, while the Spanish Crown was chiefly concerned with preventing rival European powers from gaining a foothold in the region for strategic reasons. After gaining independence, both Chile and Argentina asserted sovereignty over the territories to their south and began to colonize their Patagonian claims throughout the 19th and early 20th centuries. This expansion led to a severe decline in indigenous populations, whose societies were disrupted by settling immigrants from Argentina, the Chiloé Archipelago, mainland Chile, and Europe. Indigenous resistance to the colonization was ultimately crushed by a series of military campaigns carried out by Argentina and Chile.
Reader's Guide
Patagonia is significant as a vast, sparsely populated region at the southern tip of South America, divided between Argentina and Chile. The region's northern limit is not precisely defined, with the Colorado and Barrancas rivers commonly considered the northern limit of Argentine Patagonia, and the Huincul Fault for Chilean Patagonia. The contemporary economy of Argentine Patagonia is largely based on sheep farming and the extraction of oil and natural gas, while in Chilean Patagonia the economy is dominated by fishing, salmon aquaculture, and tourism. Due to language, culture, and location, many Patagonians do not consider themselves Latinos and proudly call themselves Patagonians instead. The region includes the archipelago of Tierra del Fuego, sometimes considered part of Patagonia, and features the largest ice fields in the Southern Hemisphere outside Antarctica. Welsh settlers established a colony in Chubut Province, and their placenames are associated with Project Hiraeth.

A Landscape Shaped by Ice, Wind, and Water
Patagonia stretches across the southern reaches of South America, straddling the borders of Argentina and Chile. The region encompasses the southern stretch of the Andes, where the western side is characterized by glacial lakes, deep fjords, and temperate rainforests, while the eastern side gives way to vast deserts, flat tablelands, and open steppes. Its boundaries are defined by two oceans—the Pacific to the west and the Atlantic to the east—and a series of southern waterways including the Strait of Magellan, the Beagle Channel, and the Drake Passage. The northern edge remains somewhat ambiguous: in Argentina, the Colorado and Barrancas rivers are commonly cited as the dividing line, encompassing provinces from Neuquén down through Santa Cruz. In Chile, geographers typically place the northern boundary at the Huincul Fault in the Araucanía Region, with the territory extending southward through Los Lagos, Aysén, and Magallanes. The Tierra del Fuego archipelago is sometimes included within Patagonia's borders as well.
Indigenous Life and the Colonial Upheaval
Before European contact, Patagonia was home to diverse indigenous communities. In a small area of northwestern Patagonia, some groups practiced limited agriculture, but across most of the territory, peoples subsisted as hunter-gatherers—traversing the eastern plains on foot and navigating the western fjords and channels in dugout canoes and dalcas. The reintroduction of the horse during the colonial era transformed northeastern groups into horseback nomads. Spanish explorers launched multiple expeditions and founded settlements, though the Crown's primary motivation was strategic: blocking rival European powers from establishing a foothold. After independence, both Argentina and Chile pushed to colonize their respective Patagonian claims throughout the 1800s and early 1900s. This wave of settlement by immigrants from Argentina, the Chiloé Archipelago, mainland Chile, and Europe caused a severe decline in indigenous populations. Resistance to colonization was ultimately suppressed through military campaigns conducted by both nations.
Names, Languages, and a Proud Identity
The name Patagonia traces back to 1520, when Magellan's expedition labeled the native inhabitants patagones, believing them to be giants—people now identified as the Tehuelche, who were notably taller than Europeans of that era. A 2011 philological report proposed an alternative origin, linking the term to Paphlagonia, an ancient Greek region in modern Turkey, possibly connected to the chivalric romance Primaleon printed in 1512. In Chubut Province, the word chupat—meaning transparency, a reference to the clarity of the river—gave rise to the province's name and its Welsh pronunciation Camwy, a legacy of Wales's Project Hiraeth. Culturally, many Patagonians reject the label Latino, preferring to identify proudly as Patagonians. This identity transcends the 1881 Boundary Treaty that split the region between Chile and Argentina. Mapuche communities, Welsh settlers, and residents of remote outposts like Laurie Island and Antarctic settlements all claim Patagonian as a patriotic, inclusive demonym rooted in shared language, culture, and place.
Two Economies, One Region
The economic character of Patagonia differs sharply between its two national halves. In Argentine Patagonia, the economy is anchored in sheep farming and the extraction of oil and natural gas, activities that have shaped the landscape and livelihoods of the eastern provinces for generations. Chilean Patagonia, by contrast, leans heavily on the sea and its visitors: commercial fishing, salmon aquaculture, and tourism form the backbone of regional income. This divergence mirrors the region's geography—the vast eastern steppes and tablelands suited to pastoral and extractive industries, versus the fjord-lined western coast and its rich marine ecosystems. The population of both Argentine and Chilean Patagonia has been tracked through successive censuses, revealing the demographic realities of a region where enormous land areas support relatively sparse communities. The economic specialization of each side—sheep and hydrocarbons in the east, fish and visitors in the west—continues to define how Patagonia engages with the wider world while remaining one of the most geographically dramatic and sparsely populated regions on Earth.
