Chuhsiungichthys is an extinct genus of ichthyodectiform ray-finned fish that lived in freshwater environments in what is now Yunnan, China, and Kyushu, Japan during the Cretaceous.[1][2][3] It differs from its sister genus, Mesoclupea, primarily by having a comparatively more anteriorly-placed dorsal fin.[4]

It contains the following species:[1]

  • †C. tsanglingensis Lew, 1974 – Turonian-Coniacian[5] of Chuhsiung, Yunnan, China (Jiangdihe Formation)
  • †C. japonicus Yabumoto, 1994 – Albian[6] of Kyushu, Japan (Kumagai Formation)
  • †C. yanagidai Yabumoto, 1994 – Hauterivian-Barremian[4][7] of Kyushu, Japan (Dobaru Formation)
