Australotitan (IPA: [au̯sˈtraːloʊtiˈtan]) is an extinct genus of possibly titanosaurian somphospondylan dinosaurs from the Late Cretaceous Winton Formation (Cenomanian–Turonian) of southern-central Queensland, Australia. The genus contains a single species, A. cooperensis, known from multiple partial skeletons. The genus Australotitan may be synonymous with Diamantinasaurus, a contemporary relative.
