Aepisaurus (/ˌiːpɪˈsɔːrəs/; derived from the Greek: αἰπεινός, aipeinós - 'lofty/high' and σαυρος, sauros - 'lizard', i.e. "lofty lizard") was a genus of sauropod dinosaur from the Albian-age Lower Cretaceous Grès vert of Département du Vaucluse, France, around 100.5 million years ago.

Despite its lack of popularity, or perhaps because of it, it has been misspelled several ways in the scientific literature, with multiple dates given to the year of description as well.

French paleontologist Paul Gervais described the new genus in 1852[1] based on a humerus found at Mont Ventoux, near Bédoin, by Prosper Renaux (1793–1852) in 1841.

A plaster cast of the complete specimen is also displayed in the Muséum national d'Histoire naturelle in Paris (MNHN 1868–242).

[4] Le Loeuff (1993), in his review of European titanosaurs, could not locate the type specimen, and found that the illustration of it did not allow it to be placed with any sauropod group.
