Buenos Aires ( /ˌbweɪnəs ˈɛəriːz/ or /-ˈaɪrɪs/ ; Spanish pronunciation : [ ˈbwenos ˈaiɾes ] ) is the capital and largest city of Argentina . The city is located on the western shore of the estuary of the Río de la Plata , on the South American continent 's southeastern coast . Buenos Aires can be translated as fair winds or good airs , but the former was the meaning intended by the founders in the 16th century , by the use of the original name Real de Nuestra Señora Santa María del Buen Ayre , named after the Madonna of Bonaria in Sardinia . The Greater Buenos Aires conurbation , which also includes several Buenos Aires Province districts , constitutes the fourth-most populous metropolitan area in the Americas , with a population of around 15.6 million . The city of Buenos Aires is neither part of Buenos Aires Province nor the Province 's capital ; rather , it is an autonomous district . In 1880 , after decades of political infighting , Buenos Aires was federalized and removed from Buenos Aires Province . The city limits were enlarged to include the towns of Belgrano and Flores ; both are now neighborhoods of the city . The 1994 constitutional amendment granted the city autonomy , hence its formal name of Autonomous City of Buenos Aires ( Ciudad Autónoma de Buenos Aires ; CABA ) . Its citizens first elected a chief of government ( i.e . mayor ) in 1996 ; previously , the mayor was directly appointed by the President of the Republic . Buenos Aires ' quality of life was ranked 91st in the world in 2018 , being one of the best in Latin America . In 2012 , it was the most visited city in South America , and the second-most visited city of Latin America ( behind Mexico City ) .
