Laguna Pargandi is a laguna (lake) located in the Patiño department of Formosa province, Argentina. Situated in the Gran Chaco region, this water body is part of a broader network of lagunas and esteros (marshes) that characterize the flat, seasonally flooded lowlands of western Formosa. The surrounding landscape is typical of the Chaco ecosystem, with a mosaic of wetlands, gallery forests, and open grasslands that support diverse aquatic and terrestrial wildlife. Neighboring water bodies include Laguna Ñacante Guazu, Laguna Satali, and a series of esteros such as Estero Yampatargui and Estero Pyraganagasat, all of which form part of the interconnected wetland system of the Patiño department.
