Bogolubovia is a genus of pterosaur from the Upper Cretaceous (early Campanian) Rybushka Formation of Petrovsk, Saratov Oblast, Russia. It is named for Nikolai Nikolaevich Bogolubov, the palaeontologist who discovered the remains in 1914. It has in 1991 been assigned to the Azhdarchidae. Wellnhofer (1991) however, retained it in the Pteranodontidae. Bogolubov had initially assigned the specimen, consisting of a single partial large cervical vertebra, as a new species of Ornithostoma, O. orientalis. It was later reclassified as a species of Pteranodon, before being assigned its own genus by Lev Nesov and Alexander Yarkov in 1989. The holotype has probably been lost, but other partial remains have been referred to the genus.
Most modern paleontologists consider it a probable member of the family Azhdarchidae. It would have been a mid-sized member of this family, with an estimated wingspan of 3-4 meters (9.8-13 feet) suggested by the holotype; a later found radius indicates a wingspan of 4.3 meters.
