The Río de la Plata Basin (Spanish: Cuenca del Plata) is the name given to the 3,100,000 km² hydrographical area that covers parts of Argentina, Brazil, Bolivia, Paraguay and Uruguay.

The precipitation falling within this area is collected by several rivers to finally reach the Río de la Plata, many of them through the Paraná River and the Uruguay River, its two most important tributaries. These rivers include the Paraguay, Pilcomayo, Bermejo, Salado, Carcarañá, Tercero, Cuarto, Iguazú, Salado del Sur, Gualeguay, Nogoyá, Mocoretá, Gualeguaychú, Miriñay, Aguapey, Negro, Guaycurú, San Javier, Guayquiraró and Samborombón.
