Chadititan is an extinct genus of titanosaurian dinosaurs from the Late Cretaceous (Campanian) Anacleto Formation of Argentina. The genus contains a single species, C. calvoi, known from several fragmentary skeletons. Chadititan is characterized by its small size compared to related taxa and its particularly gracile limbs.
