Paraguay borders on three substantially larger countries: Bolivia, Brazil, and Argentina. The country has three [[tripoint]]s: [[Hito Esmeralda|Argentina-Bolivia-Paraguay]], Bolivia-Brazil-Paraguay and [[Triple Frontier|Paraguay-Argentina-Brazil]].<ref>{{cite web | url=https://www.mre.gov.py/cndl/index.php/institucional/conceptos-claves-sobre-limites | title=Conceptos claves sobre Límites :: :: COMISIÓN NACIONAL DEMARCADORA DE LÍMITES :: }}</ref> The definition of the northwestern boundary with Bolivia, extending through the low hills of the [[Chaco (Paraguay)|Chaco]] region, dates from [[Chaco War#Aftermath|1938]]. The boundary between the Chaco and Brazil was defined in 1927; it continues from the confluence of the [[Apa River]] (''Río Apa'') and Paraguay River northward along the course of the [[Paraguay River]] to the border with Bolivia. The northern border of the Paraneña region, set in 1872, follows the course of the [[Paraná River]] (''Río Paraná''), the [[ridge]]s of the mountains in the northeast region, and finally the course of the Apa River until it empties into the Paraguay River. The large [[Argentina–Paraguay border]] comprises the [[Pilcomayo River]] (''Río Pilcomayo''), Paraná River, and Paraguay River. Argentina and Paraguay agreed on these boundaries in 1876.
