The United Provinces of the Río de la Plata or United Provinces of the River Plate, along with United Provinces in South America, are names used to refer to the emerging state that succeeded the Viceroyalty of the Río de la Plata after the May Revolution, from 1810 to 1831, encompassing the Argentine War of Independence, the Cisplatine War and the beginning of the Argentine Civil Wars. The aforementioned state is now the Argentine Republic. The name "United Provinces of the Río de la Plata" is recognised as one of the official names of Argentina according to Article 53 of its constitution.
