Araguaína is a Brazilian municipality in the state of Tocantins, in the North Region of the country. According to IBGE estimates for 2026, the municipality has 184,495 inhabitants, making it the second most populous in the state.
According to the historian Raylinn Barros da Silva, a native of Araguaína, after the state of Tocantins was created by the 1988 Constitution, Araguaína was the largest city in the state during its first years, later being overtaken in population by Palmas, a planned capital created alongside the new state. Its mesopotamian location between the federal rivers Araguaia and Tocantins, its proximity to the states of Pará and Maranhão, the strengthening of the MATOPIBA economic region and its road and rail access make the city an important regional center, standing out in commerce, education, health and services.
Araguaína lies 384 km from the capital, Palmas, 1,143 km from its former capital, Goiânia, and 1,252 km from the federal capital, Brasília. It is also close to important cities in the region, such as Imperatriz, 250 km away; Marabá, 280 km; and Belém, 842 km. In addition to the federal highway BR-153 (Belém-Brasília), the municipality is served by Araguaína Airport (IATA: AUX, ICAO: SWGN) and, since 2007, by the North–South Railway.
