This page is about the South American estuary. For the river in Puerto Rico, see Rio de la Plata (Puerto Rico). The Río de la Plata (Spanish: "Silver River") — which is often referred to in  English-speaking countries as the River Plate (as in the Battle of the River Plate), or sometimes as the [La] Plata River — is the  estuary formed by the combination of the Uruguay River and the Paraná River. It is a funnel-shaped indentation on the southeastern coastline of South America, extending from the rivers' confluence to the Atlantic Ocean.
