The Great Pampa-finch (Embernagra platensis) is a species of bird traditionally placed in the family Emberizidae. But recent reseach suggests it is either very close to the Thraupidae or even part thereof.

It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Its natural habitats are subtropical or tropical high-altitude shrubland, temperate grassland, subtropical or tropical seasonally wet or flooded lowland grassland, and swamps.
