"Eobrontosaurus" (meaning "dawn thunder lizard") is the name given to a genus of dinosaur from the Late Jurassic of North America. It was a sauropod either closely related to "Apatosaurus" or "Camarasaurus". It existed from 154.1 - 150.7 million years ago and was up to 21 to 26 meters long (68 to 78 ft).

The type species, "E. yahnahpin", was described by Filla and Redman in 1994 as a species of "Apatosaurus" ("A. yahnahpin"), but re-evaluation by Robert T. Bakker in 1998 found it to be more primitive, and so Bakker coined the new generic name "Eobrontosaurus". However, recently it has been argued that "Eobrontosaurus" actually belongs within "Camarasaurus".Upchurch, P., Barrett, P.M. and Dodson, P. (2004). "Sauropoda".
