The Atlantic Forest (Portuguese: Mata Atlântica) is a moist broadleaf forest that extends along the Atlantic coast of Brazil from Rio Grande do Norte state in the northeast to Rio Grande do Sul state in the south and inland as far as Paraguay and the Misiones Province of Argentina, where it is known as the Missionary rainforest (Spanish: Selva Misionera).
The Atlantic Forest has ecoregions within the following biome categories: seasonal moist and dry broad-leaf tropical forests, tropical and subtropical grasslands, savannas, and shrublands, and mangrove forests. The Atlantic Forest is characterized by a high biodiversity and endemism.
