Boqueirão is a municipality in the state of Paraíba, in the Northeast Region of Brazil. It is one of the many municipalities that make up the state of Paraíba, which lies in the country's northeastern area.
The municipality is located in the interior of Paraíba, within the semi-arid sertão region that characterizes much of the state's hinterland. Like other municipalities in this part of Brazil, it is situated at some distance from the state capital, João Pessoa, on the Atlantic coast.
Boqueirão is best known for the Boqueirão Reservoir (Açude Epitácio Pessoa), a large artificial lake on the Paraíba River that supplies water to the surrounding region and to the city of Campina Grande. The reservoir is a significant local landmark and shapes much of the area's geography and water supply.
