As of December 19, 2025, the Republic of Peru remains one of the most geographically fascinating and culturally rich nations in the world, a fact intrinsically tied to its precise location on the globe. Positioned strategically in the west-central part of South America, Peru serves as a dramatic convergence point for the world’s longest mountain range, the planet’s largest rainforest, and a vast, arid coastline, a unique combination that defines its climate, biodiversity, and human history.

Its location is not merely a point on a map; it is the fundamental reason behind its status as the cradle of the Inca Empire, its world-renowned cuisine, and its staggering ecological diversity. Understanding "where is Peru located" requires looking beyond simple coordinates to explore the five nations it borders and the three distinct geographical regions that carve its interior.

Peru's Geographical Profile: Location, Coordinates, and Neighbors

Peru is a large country, ranking as the third-largest nation on the South American continent, surpassed only by Brazil and Argentina. It is situated entirely in the Southern Hemisphere, though its northernmost point lies very close to the Equator, granting it a tropical influence in those regions.

Its primary geographical feature is its extensive western border along the Pacific Ocean, which stretches for over 2,400 kilometers (1,500 miles), providing a crucial maritime gateway and defining its coastal climate.

Key Geographical Facts and Coordinates

  • Continent: South America
  • Hemisphere: Southern and Western Hemispheres
  • General Location: West-central South America, bordering the Pacific Ocean.
  • Capital City: Lima (located on the central coast).
  • Geographic Coordinates (Approximate Center): 10°00′ S, 76°00′ W.
  • Total Area: Approximately 1,285,216 square kilometers.

The Five Bordering Nations (The Quintet of Neighbors)

Peru shares a significant land boundary with five different countries, giving it a total land border length of about 7,461 kilometers (4,636 miles). This network of borders connects Peru to the continent's major ecological zones, from the Amazon basin to the high-altitude Andes.

The five nations that share a border with Peru are:

  1. Ecuador: To the North.
  2. Colombia: To the North and Northeast.
  3. Brazil: To the East, sharing the largest and most remote border, traversing the Amazon rainforest.
  4. Bolivia: To the Southeast, where the border runs through the high-altitude Altiplano and includes the iconic Lake Titicaca.
  5. Chile: To the South.

The borders with Colombia and Brazil primarily traverse low ranges or tropical forests, while the borders with Bolivia and Chile are characterized by the rugged terrain of the Andes Mountains.

The Three Dramatic Geographical Regions (Costa, Sierra, Selva)

The location of Peru is best understood by dividing it into its three traditional, dramatically different longitudinal regions, which run parallel to the Pacific coast. This division results in three distinct climates, ecosystems, and cultural landscapes: the Coast, the Highlands, and the Jungle.

1. The Costa (The Arid Coast)

The Costa is a narrow, arid, and largely desert strip that runs along the entire Pacific coastline. Despite being a desert, it is the most populated region, home to the capital, Lima, and major port cities. Its climate is mild but extremely dry, a condition caused by the cold Humboldt Current (or Peru Current) flowing north from Antarctica, which prevents the formation of rain clouds.

  • Geography: Coastal desert plains, with fertile valleys created by rivers flowing down from the Andes.
  • Climate: Mild, humid, and extremely low rainfall (arid).
  • Major Cities: Lima, Trujillo, Arequipa (partially).

2. The Sierra (The Andes Highlands)

The Sierra is the central, rugged backbone of the country, dominated by the massive Andes Mountain range. This region is characterized by high peaks, deep canyons, plateaus (like the Altiplano), and dramatic elevation changes, with many peaks exceeding 6,000 meters (20,000 feet). The Andes are the source of most of Peru’s major rivers and are the historical heartland of the Inca civilization, home to sites like Machu Picchu and the Sacred Valley.

  • Geography: High mountains, inter-Andean valleys, and plateaus.
  • Climate: Temperate to cold, with a distinct wet (summer) and dry (winter) season.
  • Major Cities: Cusco, Huaraz, Puno.

3. The Selva (The Amazon Jungle)

The Selva, or the Amazon basin, covers more than 60% of Peru’s total land area, making it the largest region by far. Located on the eastern side of the Andes, this region is a vast, tropical forest that is part of the greater Amazon Rainforest. Peru holds the second-largest share of the Amazon rainforest after Brazil, making its location a crucial factor in global biodiversity and climate.

  • Geography: Dense, tropical rainforest and river networks (Amazon River system).
  • Climate: Hot, humid, and heavy rainfall (tropical).
  • Major Cities: Iquitos, Puerto Maldonado, Tarapoto.

The Impact of Peru's Unique Location on Culture and Biodiversity

Peru's geographical location—the convergence of the Pacific, the Andes, and the Amazon—is the single most important factor shaping its identity, earning it a reputation as a megadiverse country. This unique positioning creates a staggering array of microclimates and ecosystems, from glacial peaks to tropical mangroves.

The Andes Mountains, in particular, act as a massive natural barrier. Historically, this barrier led to the development of isolated cultures in the highlands, distinct from those on the coast. Today, it contributes to Peru’s incredible biodiversity, which includes thousands of species of birds, mammals, and plants, many of which are endemic.

Furthermore, the location’s influence on agriculture is profound. The diverse elevations and climates allow for the cultivation of thousands of varieties of potatoes, corn, and other native crops, directly fueling the rise of Peruvian cuisine as one of the world's most celebrated and diverse. The proximity of the cold Pacific waters, rich in nutrients due to the Humboldt Current, also sustains one of the world's most productive fishing grounds, which is vital to the national economy and the famous dish, ceviche.

In summary, the answer to "where is Peru located" is not just "South America." It is a dynamic, triangular nexus where the Pacific, the Andes, and the Amazon collide, creating a country of unparalleled geographical and cultural complexity.
