San Francisco del Monte de Oro is a village and municipality in San Luis Province, in central Argentina. It is one of the communities that make up the province's administrative structure, with both village and municipal status recognized in its designation.
The settlement lies within the central Argentine region, in a part of the country characterized by its inland location away from the Atlantic coast. San Luis Province sits in the Cuyo and central plains area of Argentina, and San Francisco del Monte de Oro forms part of that provincial territory.
Beyond its status as a village and municipality within San Luis Province, few other details are firmly established in available reference material. It should not be confused with other places bearing similar names elsewhere in Argentina or Latin America.
