Lagoa da Tijuca is a coastal lagoon located in the western zone of Rio de Janeiro, Brazil, situated within the broader Barra da Tijuca and Jacarepaguá lowland system. This brackish-to-saltwater lagoon is part of an interconnected network of lagoons and canals that includes Lagoa de Jacarepaguá and Lagoa de Marapendi, all of which share tidal influence from the Atlantic Ocean. The lagoon's position within this estuarine complex makes it a productive environment for a variety of coastal and estuarine fish species, drawing anglers who appreciate its accessible urban setting combined with genuine sportfishing opportunities.
