Rio de Janeiro, also known simply as Rio, is the capital and largest city of the state of Rio de Janeiro. It is the second-largest city in Brazil after São Paulo, and the largest by number of international tourists. It has a population of 6 million in the city proper, and 13 million in its metropolitan area as of 2025. It is also the sixth-most-populous city in the Americas.
