Ceratitoidea, formerly Ceratitaceae, is an ammonite superfamily in order Ceratitida characterized in general by highly ornamented or tuberculate shells with ceratitic sutures that may become goniatitic or ammonitic in some offshoots.

(Arkell et al. 1962) The Ceratitoidea, according to the Treatise on Invertebrate Paleontology (fig.

The Danubitidae and Aplococeratidae are combined in the Danubitaceae; the Lower Triassic Stephanitidae is reassigned to the Noritaceae, the Dinaritidae, Tirolitidae, and Hellenitidae (replaced by the Columbitidae) combined in the Dinaritaceae.

The Ceratitoidea are derived from the Permo-Scythian (Lower Trias) Xenodisciaceae (also known as the Otocerataceae), through the Dieneroceratidae, which has its origin in the upper Paleozoic prolecanitid Daraelitidae.

The Ceratitoidea is also the source for the Arpaditidae and Trachyceratidae, ancestral families for the Clydonitaceae (= Trachyceratitaceae sensu Kümmel 1952).
