The Iberá Wetlands are a mix of swamps, bogs, stagnant lakes, lagoons, natural slough, and courses of water in the center and center-north of the province of Corrientes, Argentina. Iberá is one of the most important freshwater reservoirs in South America and the second-largest wetland in the world after Pantanal in Brazil. 

Since 1982, part of the wetland is included within a provincial protected area, the Iberá Provincial Reserve, which comprises about 13,000 km2 (5,000 sq mi), the largest of such areas in Argentina. There are ongoing plans to further up its protection status to national park.
