Montecarlo is a village and municipality in Misiones Province, in north-eastern Argentina. It is one of the communities that make up this province, which lies in the country's far north-east and borders Paraguay and Brazil.
As a municipality, Montecarlo serves as a local administrative unit within Misiones, with both village and municipal functions. The surrounding province is known for its subtropical climate and its position within the Paraná River basin, though the settlement itself is a small population centre rather than a major urban area.
Details about Montecarlo's founding, economy, and attractions are limited in readily available sources; the settlement is chiefly identified by its status as a village and municipality within Misiones Province.
