Buenos Aires, city and capital of Argentina. The city is coextensive with the Federal District (Distrito Federal) and is situated on the shore of the Río de la Plata, 150 miles (240 km) from the Atlantic Ocean. Buenos Aires is one of Latin America’s most important ports and most populous cities, as well as the national centre of commerce, industry, politics, culture, and technology. According to tradition, Spanish colonizer Pedro de Mendoza established the first settlement there, which he named Nuestra Señora Santa María del Buen Aire (“Our Lady St. Mary of the Good Air”). Buenos Aires locals are referred to as porteños (“people of the port”) because so many of the city’s inhabitants historically arrived by boat from Europe.
