The Brazilian Highlands or Brazilian Plateau (Portuguese: Planalto Brasileiro) is an extensive geographical region covering most of the eastern, southern and central portions of Brazil, in all some 4,500,000 km2 (1,930,511 sq mi) or approximately half of the country's land area.

[1][2] The vast majority of Brazil's population (203.062.512; 2022 census) lives in the highlands or on the narrow coastal region immediately adjacent to it.

Erosion has also played a large part in shaping the Highlands, forming extensive sedimentary deposits and wearing down the mountains.

The Brazilian Highlands are recognized for its great diversity: within the region there are several different biomes, vastly different climatic conditions, many types of soil, and thousands of animal and plant species.

Some of the most important are (from north to south): The highest point of the Brazilian Highlands is the Pico da Bandeira in the Serra do Caparaó, 2,891 meters (9,485 ft).
