Sultanuvaisia is an extinct genus of ichthyodectiform ray-finned fish from the Late Cretaceous of Kyzyl Kum, central Asia. It was named by Lev Nesov in 1981.{{cite journal |last=Nesov |first=Lev A. |year=1981 |title=[Flying reptiles from the Late Cretaceous of Kyzyl-Kum] |journal=Paleontologicheskii Zhurnal |volume=15 |pages=98–104 |language=Russian}} At first, he tentatively described the fossil material as jaw fragments of a ctenochasmatid pterosaur (a flying reptile), but reinterpreted Sultanuvaisia as a fish in 1986.{{cite book |last=Nesov |first=Lev A. |year=1986 |chapter=[The first finding of the Late Cretaceous bird Ichthyornis in the old world and some other bird bones from the Cretaceous and Paleogene of Middle Asia] |pages=31–38 |editor=Potapova, R.
