The Paraguay campaign (1810-1811) was a military expedition launched by Buenos Aires and commanded by Manuel Belgrano to ensure the adherence of the Intendency of Paraguay to the Primera Junta, which was established after the May Revolution. It is considered both a part of the independence of Argentina and Paraguay.

The first battles fought were the Battle of Campichuelo and Battle of Campo Maracana, in which the Junta of Buenos Aires army claimed victory. However, they were completely vanquished in the subsequent Battle of Paraguarí and Battle of Tacuarí. The campaign ended in a military failure and Paraguay breaking its links with the Spanish crown just two months after Belgrano's withdrawal, starting its course towards full independence.
