Amargasuchus is an extinct genus of crocodylomorph. It was a member of the Trematochampsidae, an enigmatic family of mesoeucrocodylians. Fossils have been found from the La Amarga Formation in Argentina and date back to the Barremian and Aptian stages of the Early Cretaceous. Amargasuchus inhabited a terrestrial paleoenvironment that existed during the Early Cretaceous in the Neuquén basin and was characterized by a system of braided rivers, lakes, and alluvial plains. Sauropod, abelisauroid, and stegosaurian dinosaurs have also been found existing in the Neuquén basin at this time.
The holotype was discovered in 1984 in association with the dicraeosaurid sauropod dinosaur Amargasaurus.
