The Humid Chaco (Spanish: Chaco Húmedo or Chaco Oriental) is a tropical grasslands, savannas, and shrublands ecoregion in South America. It lies in the basin of the Paraná River, covering portions of central Paraguay and northern Argentina, and with a small portion of southwestern Brazil and northwestern Uruguay. The natural vegetation is a mosaic of grasslands, palm savanna, and forest.
