Kogaionon is a mammal genus from the Upper Cretaceous of Romania. It lived in Transylvania at the same time as some of the last dinosaurs and was a member of the extinct order of Multituberculata. It was named after the holy mountain of the ancient Dacians.

For those of a technical inclination, it's within the suborder of Cimolodonta, and the family Kogaionidae.
