Açude Pacoti is a reservoir located in the state of Ceará, Brazil, situated within the drainage basin of the Rio Pacoti. The Rio Pacoti originates in the Serra de Baturité mountain range in the municipality of Guaramiranga and travels approximately 150 kilometers before reaching the Atlantic Ocean at the border of Fortaleza and Aquiraz. The açude sits along this river system, which also includes the Açude Acarape do Meio, and the broader watershed touches several municipalities across the interior of Ceará, including Acarape, Guaiúba, Pacajus, Horizonte, Itaitinga, and Eusébio. The reservoir is part of a river system that ultimately drains into a coastal zone protected by the Área de Proteção Ambiental do Rio Pacoti near Praia de Porto das Dunas, reflecting the ecological significance of this watershed to the greater Fortaleza metropolitan region.
