Ctenodentex is an extinct genus of prehistoric seabream from the middle Eocene of Europe.

[1][2] It contains a single species, C. laekeniensis, from the Bartonian-aged Wemmel Member of the Maldegem Formation in Belgium.

[3][4][5] It was initially described as Dentex laekeniensis before being placed in its own genus, Ctenodentex, although some authors continue to classify it in Dentex.

[3] Plesioserranus Casier, 1966, a putative serranid from the same formation which only contains the single species P. wemmeliensis Storms, 1896 (=Serranus wemmeliensis Storms, 1896), was found to be synonymous with C. laekeniensis based on their identical otolith morphology.
