Bravasaurus (meaning Laguna Brava lizard) is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Ciénaga del Río Huaco Formation of La Rioja, Argentina.

The specific name refers to the people, the arriero or drivers in Spanish, who carried cattle through the Andes in the 19th century.

[1] It is known from the holotype CRILAR-Pv 612, which consists of the right quadrate and quadratojugal, four cervical, five dorsal, and three caudal vertebrae, few dorsal ribs, three haemal arches, the left humerus, a fragmentary ulna, the metacarpal IV, a partial left ilium with sacral ribs, the right pubis, a partial ischium, the left femur, and both fibulae, and the paratype CRILAR-Pv 613, which consists of an isolated tooth, the right ilium, the right femur, and dorsal ribs.

[1] The describers' phylogenetic analysis places Bravasaurus as a derived member of the Lithostrotia, in the clade Aeolosaurini, which they recover as a subclade of Rinconsauria, different from other cladograms.
