Approximately 60% of the Amazon Rainforest lies within Brazil.
The Amazon Rainforest covers much of the Amazon Basin in South America, extending across Brazil, Peru, Colombia, Bolivia, Venezuela, Guyana, Suriname, and French Guiana. Brazil contains the largest share of this immense forest, especially across the states of Amazonas, Pará, Mato Grosso, Acre, and Rondônia.
The Brazilian portion is often associated with the Legal Amazon, a broader administrative region created by the Brazilian government for planning and development. The Legal Amazon is larger than the rainforest itself because it includes areas of cerrado grassland and other ecosystems. This distinction can cause confusion when comparing maps and statistics.
Brazil’s Amazon forest is important for regional rainfall, river systems, biodiversity, Indigenous communities, and global climate processes. However, the exact percentage can vary slightly between sources because researchers use different boundaries for the Amazon biome, basin, and rainforest. The commonly cited figure remains about 60% within Brazil.
