Chubutisaurus (meaning "Chubut lizard") is a genus of dinosaur from the Early Cretaceous Period. It lived in South America. It is classified as a sauropod, specifically one of the titanosaurs. The type species, Chubutisaurus insignis, was described by del Corro in 1975. Its fossils were found in the Cerro Barcino Formation, Albian stage, about 110 million years ago. Chubutisaurus had a more robust radius than Venenosaurus.
