Paranasuchus is an extinct genus of large caiman from the Late Miocene Ituzaingó Formation of Argentina. The type species was originally described as a new species of Caiman, C. gasparinae, in 2013, but a study from 2024 concluded that it differed significantly enough to represent its own genus. Paranasuchus was a large caiman with a broad skull and was only one of several generalized caimans that inhabited Paraná during the Late Miocene.
