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.

[1] At first, he tentatively described the fossil material as jaw fragments of a ctenochasmatid pterosaur (a flying reptile),[1] but reinterpreted Sultanuvaisia as a fish in 1986.

[2] The type species is S.
