Argentina–Paraguay border

The Argentina–Paraguay border is the line that limits the territories of Argentina and Paraguay. This boundary is solely defined by three major rivers: the Pilcomayo, Paraná and Paraguay, being one of the largest natural borders in the world. The capital of Paraguay, Asunción, lies on one of the banks of the Paraguay River, which borders Argentina. The capital of Argentina is Buenos Aires, which lies on one of the banks of the River Plate, made by major Paraguayan tributaries. Argentina is the country which Paraguay has the largest border with, being about 1,689 km long. It is Argentina's second largest border, after the Argentina–Chile border.
