Teresina is the capital and most populous municipality in the Brazilian state of Piauí. Being located in north-central Piauí 366 km from the coast, it is the only capital in the Brazilian Northeast that is not located on the shores of the Atlantic Ocean. With 902.644 inhabitants, Teresina is the 19st largest city in Brazil, and the 16th largest state capital in the country.^[3] Together with Timon in the neighbouring state of Maranhão, it forms a conurbation with a population of about 2.729.527 inhabitants; the entire metropolitan region of Teresina has over 2.893.729 inhabitants.^[4] The only natural barrier that separates Teresina from Timon is the Parnaíba river, one of the largest in the Northeast.

Teresina is the capital with the first best quality of life in the North-Northeast according to FIRJAN^[5] and the 4th in Brazil. It is among the 50 cities in the world with the highest murder rates, with 315 homicides in 2017.^[6]

Its motto is the Latin phrase Omnia in Charitatis, which means, in English, "All for charity". The city is the birthplace of, among others, Torquato Neto, who belonged to the Tropicalismo movement.

Its cathedral, Catedral Metropolitana Nossa Senhora das Dores, dedicated to Our Lady of Sorrows, is the archiepiscopal see of the Roman Catholic Archdiocese of Teresina.

Teresina was founded on August 16, 1852, under the name of Vila Nova do Poty (because its origin is linked to the Poti river) as the capital of the state of Piauí. It was the first planned city in the Brazil and the only northeast capital located out of the coast. Until 1852, Oeiras was the capital of the Piauí Captaincy. However, due to difficulties in communication and trade, the capital was transferred to an area next to the Parnaíba River, to the other cities and to the sea coast. Colonization of the area where Teresina is now located dates back to the 18th century. The chosen place was a small community of fishermen, in 1760, nearby Poty and Panaíba rivers, which grew into a village called "Vila do Poty", but, due to the inundation of the Parnaíba River riverbanks, the city had to be built in a higher position.

In the 19th century, it was initially called Vila Nova do Poty, but later the city was renamed Teresina, in honor of Empress Teresa Cristina, the wife of Emperor Pedro II of Brazil.

Teresina is the hottest city in the country and the city with the third-highest incidence of lightning in the world. Nowadays^[when?], Teresina's economy is based on international manufacturing industries and trade.

Located in a transition zone between the northeast and the Amazon (Mid-North), Teresina is surrounded by mata dos cocais, savannas and cerradões where many carnaúba, babaçu, buriti palms, jatobás, ipês, and many other medium-sized trees can be seen. In the region there are also remnants of Teresina Atlantic Forest, which makes the landscape shrub coverage very rich and dense.

Teresina has a tropical wet and dry climate (Köppen climate classification: Aw) with semi-humid characteristics and two seasons: the rainy season (which occurs in summer and autumn of the southern hemisphere) and the dry season (which occurs in winter and spring).

This period is referred to as "Bro" by locals as the hottest months end with -bro in Portuguese: setembro, outubro, novembro, and dezembro. A peculiar feature of the rains in the city are their speed and intensity, with strong winds, large force of water and very common lightning. The annual rainfall stands at around 1,325 millimetres or 52 inches. The highest recorded daily precipitation was 125 millimetres (5 in).^[7]
