Venenosaurus (vahr-AN-oh-SAWR-us) is named after the Poison Strip Member of the Cedar Mountain Formation in Utah, where the fossils were discovered by Tidwell, Carpenter & Meyer in 2001. Venenosaurus is a relatively small (probably around 10 metres (33 ft) long) titanosauriform sauropod, known from an incomplete skeleton of a single individual.

Venenosaurus was a plant-eating dinosaur (a titanosaurid sauropod) from the early Cretaceous period. It was a long-necked, long-tailed dinosaur and was named by paleontologists Tidwell, Carpenter, and Meyer in 2001; the type species is V. dicrocei.
