Rio Branco is the capital of the Brazilian state of Acre, in the North Region of the country. Located 3,030 kilometres from Brasília, it is the westernmost state capital in Brazil and lies on the banks of the Acre River.
Its population in the 2022 Census of the Brazilian Institute of Geography and Statistics (IBGE) was 364,756 inhabitants, making Rio Branco the seventh most populous municipality in the North Region of Brazil. Its territorial area is 8,834.832 km², making it the fifth largest municipality in the state by territorial area. The IBGE estimate for 2025 indicated 389,001 inhabitants. Of this total area, 44.9559 km² lie within the urban perimeter, which ranks Rio Branco as the 62nd largest in the country.
As the fourth oldest capital in the North Region of Brazil, after Belém, Manaus and Macapá, Rio Branco was settled at the end of the 19th century with the arrival of people from the Northeast. The development of the municipality took place over a long period driven by the Rubber Cycle. During this period there was also intense miscegenation of the population, with the union of white Northeasterners of Portuguese ancestry, Afro-Brazilians and Indigenous peoples, mainly of the Culina ethnic group, together with peoples coming from other regions of the world, mainly Spaniards, Portuguese, Lebanese, Italians and Turks.
