Arrudatitan is an extinct genus of titanosaur sauropod dinosaur known from the Late Cretaceous (Campanian-Maastrichtian)-aged Adamantina Formation of Brazil. The type species, A. maximus, was named and described in 2011 as a species of Aeolosaurus, but was separated into its own genus in 2021. It was relatively gracile for a titanosaur.
