Palmas (Brazilian Portuguese pronunciation: [ˈpawmɐs], Palm trees; Akwẽ-Xerénte: Akwẽ krikahâzawre wam hã [akwẽ kɾikahəʐawɾɛ wam hə̃]) is the capital and largest city of the state of Tocantins, Brazil. According to IBGE estimates from 2020, the city had 306,296 inhabitants. Palmas has a metropolitan area with 471,639 inhabitants.
Palmas was founded in 1990 and developed from the ground up in a former agricultural area as the capital of the new state of Tocantins, formed under the 1988 constitution. It was intended to develop a relatively undeveloped area of the nation to provide better jobs for people. The city has a well-designed road system, and its urban zoning is modeled on that of Brasília, the national capital. A symmetrical park lies at the city centre, and a large central avenue similar to Brasília's Monumental Axis extends north to south. The city is home to the Federal University of Tocantins.
