Aconquija is the only National Park (NP) in the province of Tucumán and one ofthe most importants in northwestern Argentina. It is the NP with wider altitudinalgradient in the country (Administración de Parques Nacionales, 2023), ranging from511 to 5450 M a.s.l.. Given that this NP was recently created, most of its territoryhas yet to be investigated regarding its diversity of species. Water bodies in this areaare represented by mountain rivers and streams draining to the Salí-Dulce Riverbasin. The current study provides a species list of freshwater fishes inhabiting theAconquija National Park. We examined 427 specimens, distributed in five orders,ten families and 20 species
