The Misiones Orientales (or Siete Pueblos de las Misiones (pronounced as /es/, Sete Povos das Missões (pronounced as /pt/,) was a region in South America where a group of seven indigenous villages were founded by Spanish Jesuits in present-day Rio Grande do Sul, the southernmost State of Brazil.

Between 1609 and 1756, Misiones Orientales formed part of the Jesuit Reductions, together with present-day Misiones Province in Argentina and the former Misiones Department in Paraguay (later subdivided into Misiones and Itapúa). This was a territory almost fully independent from Spanish and Portuguese rule, created and ruled by Jesuit missionaries to the local Guaraní people.[1] It was famous for its resistance to enslavement and egalitarian laws based on the Bible.
The King of Spain was the nominal ruler of these lands and in the Treaty of Madrid (1750) he gave the eastern part of the Jesuit Reductions to Portugal. The seven Jesuit missions here were to be dismantled and relocated on the Spanish western side of the Uruguay River.[2] The Guarani people living there refused, which led to the Guarani War, won by Portugal and Spain.
The territory returned to Spain in 1777 in the First Treaty of San Ildefonso, but was definitively ceded to Portugal in the Treaty of Badajoz (1801).[2] It became part of Brazil when Brazil gained independence from Portugal in 1822.
