The Río de la Plata—sometimes called River Plate in British English —is a river in Argentina. It is made from the Uruguay River and the Paraná River. These rivers are on the border between Argentina and Uruguay. It is about 290 kilometres (180 mi) long.

The Río de la Plata widens from about 2 kilometres (1.2 mi) at the inner part to about 220 kilometres (140 mi) at its mouth.[4] Buenos Aires is on its western shore. Montevideo is on its northern shores.

The Río de la Plata is home for the Loggerhead Sea Turtle, Green Sea Turtle, Leatherback Sea Turtle, the rare La Plata Dolphin, and many species of fish.
