Parnaíba
municipality of Piauí state, Brazil
Parnaíba (Portuguese: [paʁnaˈibɐ]) is a city in the Brazilian state of Piauí. Having a population of over 170,491 inhabitants according to IBGE's 2025 estimates, it is the second most populous city in the state, after the capital Teresina. It is one of the four coastal municipalities in Piauí (besides Ilha Grande, Luís Correia, and Cajueiro da Praia), all of which make up the city's metropolitan area.
Besides the natural environment, Parnaíba has historical value for Piauí; near Porto das Barcas several historic buildings reflect the importance of Parnaíba, coming at that time to be more important than the former capital Oeiras and taking up same references in Europe.
History
In 1699, the region between the Igaraçu river and the Serra da Ibiapaba, inhabited by indigenous people, was pioneered by Leonardo de Sá and his companions, who obtained a land grant on the banks of that river.
Under the name of Parnaíba, toponym that arose, according to some, from the desire of the first explorers of Piauí to pay homage to the then São Paulo district of Parnaíba, and, according to others, from the Tupi word that means 'great unnavigable river'.
From 1761 onwards its development began. At that time, there was a charqueada owned by Domingos Dias da Silva, Portuguese founder of Porto das Barcas and pioneer in the region, mainly in the commercial and agricultural sectors.
The governor of the province, colonel João Pereira Caldas, was installed in the municipality in 1762, which has a name of São João da Parnaíba.
