The Portuguese conquest of the Banda Oriental was the armed-conflict that took place between 1816 and 1820 in the Banda Oriental, for control of what today comprises the whole of the Republic of Uruguay, the northern part of the Argentine Mesopotamia and southern Brazil. The four-year armed-conflict resulted in the annexation of the Banda Oriental into the United Kingdom of Portugal, Brazil and the Algarves as the Brazilian province of Cisplatina.

The belligerents were, on one side, the "Artiguistas" led by José Gervasio Artigas and some leaders of other provinces that made up the Federal League, like Andrés Guazurary, and on the other, the troops of the United Kingdom of Portugal, Brazil and the Algarves, directed by Carlos Frederico Lecor.

On the naval front, the conflict far exceeded the Río de la Plata and the Argentine coast to spread globally, as the Insurgent privateers, most notably under the flag of Buenos Aires and flag of Artigas, harassed Portuguese ships in Europe, Africa and the Caribbean.^{[citation needed]}

The occupation of the Banda Oriental by the United Kingdom of Portugal, Brazil and the Algarves, replaced by the Empire of Brazil in 1824, lasted until 1828.
