Cretatriacanthus is an extinct genus of prehistoric marine ray-finned fish from the Late Cretaceous. It contains a single species, C. guidottii from the late Campanian or early Maastrichtian of Nardò, Italy.[2] It is generally placed as a basal tetraodontiform,[3][4] although more recent studies have disputed this, finding it to instead represent an early basal percomorph (under an expanded treatment of Acanthuriformes).[5]

It can be distinguished by its tall dorsal fin of elongated spines, which shows similarities to that of the modern genus Triacanthus. Spines are also present on its pelvic fins.[1]
