Stretching across the northern third of South America, the Amazon rainforest forms the world's largest and most biodiverse tropical forest. Understanding which countries the Amazon rainforest covers is essential to grasp the scale of its ecological importance and the challenges it faces. This vast ecosystem is not confined to a single nation but spans multiple sovereign territories, each managing a unique portion of this critical environmental asset.
Primary Countries of the Amazon Basin
The majority of the Amazon rainforest lies within the borders of just nine countries, with one nation holding the largest share. Brazil contains approximately 60% of the total Amazon area, making it the undisputed custodian of this vital region. The forest extends deeply into Peru, which accounts for about 13%, and Colombia, which holds around 10% of the basin.
Brazil: The Dominant Custodian
Within Brazil, the Amazon covers a significant portion of the northern states, including Amazonas, Pará, and Mato Grosso. This immense Brazilian portion is crucial for global climate regulation and houses countless indigenous communities. The policies enacted within this vast area have direct consequences for deforestation rates worldwide.
Peru and Colombia: Key Biodiversity Hubs
Peru's Amazon region is renowned for its incredible species richness and includes major rivers like the Ucayali and Marañón. Colombia's Amazon, though smaller in total area, is exceptionally rich in endemic plants and animals, connecting the Andes to the Brazilian lowlands. Both countries play a vital role in maintaining the hydrological cycle of the entire continent.
Other Nations with Amazon Territory
Beyond the top three, the rainforest extends into several other South American nations, contributing to their unique ecological and cultural heritage. These countries manage smaller but still significant portions of the basin, adding to the overall complexity of Amazon conservation efforts.

Geographic Scope and Significance
The Amazon basin covers approximately 7 million square kilometers, with the rainforest itself occupying about 5.5 million square kilometers. This immense area crosses numerous time zones and encompasses a wide variety of landscapes, from lowland floodplains to towering Andean foothills. The table below outlines the approximate percentage of the Amazon rainforest contained within each country.
