Cyranorhis is an extinct genus of marine ray-finned fish that lived during the Serpukhovian age of the Carboniferous period.

One species is known, C. bergeraci in the Bear Gulch Limestone what is now Montana, United States.

[1][2] It is named after French novelist Cyrano de Bergerac.

[3] It is a member of the Rhadinichthyidae, a family of basal ray-finned fish that was formerly placed in the now-paraphyletic order Palaeonisciformes.

[4] Based on the cladistic analysis by Ren & Xu, Cyranorhis was recovered in a sister group relationship with the Triassic Pteronisculus which may thus represent a late-surviving rhadinichthyid.
