Riojasauridae is a family of sauropod-like dinosaurs from the Upper Triassic. It is known primarily from the genera "Riojasaurus" and "Eucnemesaurus". Sites containing Riojauridae include the Lower Elliot Formation of Orange Free State, South Africa (where fossils of "Eucnemesaurus" have been found), and Ischigualasto, in La Rioja Province, Argentina ( where fossils of "Riojasaurus" have been recovered).clade|style=font-size:80%;line-height:50%
