The Copa Campeonato del Río de la Plata (English: Río de la Plata Championship Cup) was an official association football club competition. Unlike Copa Aldao (organised by the Argentine and Uruguayan Associations together), this cup was contested by champions of dissident associations, in this case Asociación Amateurs de Football (AAmF) and Federación Uruguaya de Football (FUF). In the match, played at Gimnasia y Esgrima Stadium in Palermo, Buenos Aires on June 22, 1924, San Lorenzo beat Wanderers 1–0, winning not only the trophy but their first international title.
