Chubutisaurus (meaning "Chubut lizard") is a genus of somphospondylan sauropod dinosaur from the Early Cretaceous Cerro Barcino Formation (Albian) of Argentina.

[1] The type species, Chubutisaurus insignis, was described by del Corro in 1975.

[2][3] Chubutisaurus had a more robust radius than Venenosaurus.

[4] In 2010 Gregory Paul gave a length of 18 meters (59 ft) and a weight of 12 tonnes (13.2 short tons).

[5] Thomas Holtz estimated its length at 23 meters (75.5 ft) in 2012.
