Mariscal Estigarribia (Spanish pronunciation: [maɾisˈkal estiɣaˈriβja]) is a town in the Boquerón Department, Paraguay.

Mariscal Estigarribia is home to Dr. Luis María Argaña International Airport (IATA code: ESG),[1] which some media reports[who?]

[2] The Clarín newspaper reports that Mariscal Estigarribia would be a strategic location for a military base because of its proximity to the Triple Frontera between Paraguay, Brazil and Argentina; the Guarani aquifer; and Bolivia (less than 200 km at a time when "Washington's magnifying glass goes on the Altiplano and points toward Venezuelan Hugo Chávez—the regional demon according to Bush's administration—as the instigator of the instability in the region".
