Rio de Janeiro, in full Cidade de São Sebastião do Rio de Janeiro, byname Rio, city and port, capital of the estado (state) of Rio de Janeiro, Brazil. It is located on the Atlantic Ocean, in the southeastern part of the tropical zone of South America, and is widely recognized as one of the world’s most beautiful and interesting urban centres. Although Rio de Janeiro continues to be the preeminent icon of Brazil in the eyes of many in the world, in reality its location, architecture, inhabitants, and lifestyle make it highly unique when compared with other Brazilian cities, especially the country’s capital of Brasília or the much larger city of São Paulo. The former is a much smaller city dating back only to the 1960s, while the latter is a huge, sprawling commercial and manufacturing centre with none of Rio’s spectacular natural beauty or captivating charm. Unlike Rio, both are located on flat interior plateaus.
The name was given to the city’s original site by Portuguese navigators who arrived on January 1, 1502, and mistook the entrance of the bay for the mouth of a river (rio is the Portuguese word for “river” and janeiro the word for “January”). When the foundations of the future town were laid in 1565, it was named Cidade de São Sebastião do Rio de Janeiro (“City of St. Sebastian of Rio de Janeiro”) for both São Sebastião and Dom Sebastião, king of Portugal.
