Olorotitan is a monotypic genus of lambeosaurine duck-billed dinosaur, containing a single species, O. arharensis. It was among the last non-avian dinosaurs to go extinct during the Cretaceous–Paleogene extinction event, having lived from the middle to late Maastrichtian age of the Late Cretaceous period. The remains were found in the Udurchukan Formation beds of Kundur, Arkharinsky District, Amur Oblast, Eastern Russia, in the vicinity of the Amur River.
