The Corrientes campaign or the Paraguayan invasion of Corrientes was the second campaign of the Paraguayan War. Paraguayan forces occupied the Argentinian city of Corrientes and other towns in Corrientes Province. The campaign occurred at the same time as the Siege of Uruguaiana.

Argentina and Uruguay declared war against the Paraguayan invaders, who were already at war with the Empire of Brazil, and signed the Treaty of the Triple Alliance. The Paraguayan invasion of Argentina failed, but led to the invasion of Paraguay in later campaigns.
