The "selva parananese" or Upper Paraná Atlantic Forest is an ecoregion of the tropical moist forests biome and the South American Atlantic Forest biome. The ecoregion stretches across the borders of southern Brazil, eastern Paraguay and northeastern Argentina.

The "selva parananese" or Upper Paraná Atlantic Forest (also known as the Alto Paraná Atlantic forests or Paraná-Paraíba interior forests) is an ecoregion of the tropical moist forests biome and the South American Atlantic Forest biome. The ecoregion stretches across the borders of southern Brazil, eastern Paraguay and northeastern Argentina.

The ecoregion covers portions of the Brazilian states of Rio de Janeiro, Minas Gerais, São Paulo, Goiás, Mato Grosso do Sul, Paraná, Santa Catarina, and Rio Grande do Sul, the Argentinian province of Misiones, and the Paraguayan departments of Alto Paraná, Amambay, Caaguazu, Caazapa, Canindeyú, Concepción, Guairá, and Itapúa.

The Upper Paraná Atlantic Forest is not only one of the most biologically important ecosystems in the world, it is also one of the most endangered rain forests. It houses an impressive variety of species - some 450 different trees can be found in only one hectare for example - and hosts animals and plants found nowhere else. Over 90% of all amphibians and 50% of all plants found in the forest are endemic, meaning they cannot be found anywhere else.

The climate of the ecoregion is subtropical, with 1,200 to 1,600 mm (47 to 63 in) of rainfall per year. The winter dry season extends from April to September.
