The Southern Cone (Spanish: Cono Sur, Portuguese: Cone Sul) is a geographical and cultural subregion composed of the southernmost areas of South America, mostly south of the Tropic of Capricorn. Traditionally, it covers Argentina, Chile, and Uruguay, bounded on the west by the Pacific Ocean and on the east by the Atlantic Ocean. In terms of geography, the Southern Cone comprises Argentina, Chile, Uruguay and Paraguay, and sometimes includes Brazil's four southernmost states (Paraná, Rio Grande do Sul, Santa Catarina, and São Paulo).
The Southern Cone is the subregion with the highest Human Development Index, and highest standard of living in Latin America.
