Argentina is divided into 23 provinces and one autonomous city, Buenos Aires, which serves as the federal capital of the country. Here is a list of the 23 provinces in alphabetical order.
Argentina is the second-largest country in South America, stretching from the subtropical north down to Patagonia and the southern tip of the continent. It borders Chile, Bolivia, Paraguay, Brazil, and Uruguay, with a long coastline along the Atlantic Ocean. The country is divided into 23 provinces and 1 autonomous city, and those provinces are further divided into departments and municipalities. Buenos Aires is the national capital and also the largest city in the country.
The geography changes dramatically across Argentina. You’ll find tropical forests in the north, fertile plains in the Pampas region, towering Andes mountains in the west, and cold windswept landscapes in Patagonia. Most of the population lives in the central and eastern parts of the country, especially around Buenos Aires.
