Chromogisaurus is a sauropodomorph which existed in Argentina during the late Triassic period. It was a herbivore about 2 metres (6 ft 7 in) in length, and was optionally quadrupedal.

Chromogisaurus was first named by Martin Daniel Ezcurra in 2010, and the type species is Chromogisaurus novasi. The generic name is derived from Greek chroma, "colour", and ge, "earth", a reference to the Valle Pintado, the "Painted Valley". The specific name honours Fernando Emilio Novas. The holotype, PVSJ 846, was found in a layer of the Ischigualasto Formation dating from the Carnian. This makes Chromogisaurus one of the oldest known dinosaurs. The specimen consists of a partial skeleton lacking the skull, with elements of the front and hind limbs, as well as the pelvis and two caudal vertebrae.

A cladistic analysis by Ezcurra indicated that Chromogisaurus was a member of a clade basal sauropodomorphs, the Guaibasauridae, together with Guaibasaurus, the disputed Agnosphitys, Panphagia and Saturnalia. Within Guaibasauridae, it forms a smaller clade with its sister taxon Saturnalia, the Saturnaliinae.
