Parnaíba is a port city in Piauí, Brazil, on the right bank of the Parnaíba River, 400 km. below the capital, Teresina.
Parnaíba is situated at the point where the most easterly of the delta outlets, or channels, called the Rio Iguarassfl, branches off from the main stream. All the outlet channels of the river are obstructed by bars built up by the strong current along the Atlantic coast, and only vessels of light draught can enter. The town has some well-constructed buildings of the old Portuguese type, including two churches and a fine hospital. Parnaíba is the commercial entrept of the state; its exports go chiefly through the small port of Amarracao, at the mouth of the Rio Iguarassfl, 18 km. distant.
