Estadio Monumental (Spanish pronunciation: [esˈtaðjo monumenˈtal anˈtonjo βesˈpusjo liˈβeɾti]), officially Estadio Mâs Monumental for sponsorship reasons, and popularly known as "River Plate Stadium", "Monumental de Núñez", or simply "El Monumental", is a stadium in Belgrano, Buenos Aires (although popular belief wrongly states that the stadium is in the Núñez district), home venue of Club Atlético River Plate.

It hosted the 1978 FIFA World Cup Final between Argentina and the Netherlands. Additionally, it hosted four finals of the Copa América, most recently in 2011.
