The Argentine Confederation (Spanish: Confederación Argentina) was the last predecessor state of modern Argentina; its name is still one of the official names of the country according to the Argentine Constitution, Article 35. It was the name of the country from 1831 to 1852, when the provinces were organized as a confederation without a head of state. The governor of Buenos Aires Province (Juan Manuel de Rosas during most of the period) managed foreign relations during this time, Under his rule, the Argentine Confederation engaged in conflicts with Brazil, Bolivia, Uruguay, France and the United Kingdom, as well as other Argentine factions during the Argentine Civil Wars.

Rosas was ousted from power in 1852 by Justo José de Urquiza, after the battle of Caseros. Urquiza convened the 1853 Constituent Assembly to write a national constitution. Buenos Aires resisted Urquiza and seceded from the Confederation in 1852, becoming the State of Buenos Aires; the province would return to Argentina in 1861.
