Tataouinea is an extinct genus of sauropod dinosaur in the subfamily Rebbachisaurinae of Rebbachisauridae which lived in the Early Cretaceous of Tunisia.

[2] The first known elements of the holotype were discovered in the Aïn el Guettar Formation in 2011 by Aldo Luigi Bacchetta, but he was unable to excavate the specimen until 2012.

Its bones were extensively pneumatic, providing strong support for the theory that sauropods had birdlike respiratory systems.

[2] A phylogenetic analysis was published alongside the paper, finding a clade of nigersaurines to include Rebbachisaurus, thus forcing the subfamily to be renamed Rebbachisaurinae.

[3] Amazonsaurus Zapalasaurus Histriasaurus Comahuesaurus Cathartesaura Limaysaurus Katepensaurus Nigersaurus Rebbachisaurus Demandasaurus Tataouinea Tataouinea was discovered in the Jebel El Mra Member or the nearby Oum ed Diab Member of the Aptian-Albian Aïn el Guettar Formation.
