Ctenodentex is an extinct genus of prehistoric seabream from the middle Eocene of Europe. It contains a single species, C. laekeniensis, from the Bartonian-aged Wemmel Member of the Maldegem Formation in Belgium. It was initially described as Dentex laekeniensis before being placed in its own genus, Ctenodentex, although some authors continue to classify it in Dentex.
