Piauí is one of the 26 states of Brazil. It is in the northeastern part of the country. The capital of Piauí is Teresina.


Piauí shares borders with the states of Maranhão (west), Ceará (east), Pernambuco (east) and Bahia (east and south). It borders the Atlantic Ocean to the north.

Piauí has the shortest coastline of any of the Brazilian states that borders the Atlantic Ocean. Its coastline is only 66 km long. The capital, Teresina, is the only state capital in the northeast that is not on the coast. The reason for this is because, unlike the rest of the area, Piauí state was first colonised away from the coast and slowly expanded towards the ocean. The other states in the area started on the coast and grew inland.


The flag of Piaui was created on 24 July 1922. The blue canton and a star is for the state itself. The green and yellow stripes are for Brazil.
