Cheiloceratidae is a family of ammonoid cephalopods included in the goniatitid suborder Tornoceratina in which the suture has 4 to 12 lobes, the ventral one undivided and those in the lateral areas originating as subdivisions of internal and external lateral saddles.

The taxonomy of the Cheiloceratidae varies according to the perception of different researchers over time and can be considered a work in progress.

Cheiloceratinae is essentially the Cheiloceratidae of Saunders et al.[2] but includes Dimeroceras, the basis for the Dimeroceratidae and ultimately the Dimeroceratoidea.

[3] The Russian Osnovy Paleontologii, by Bogoslovsky et al,[4] placed the Cheiloceratidae, in the sense of the Cheiloceratinae of the Treatise, in the superfamily Dimeroceratoidea (ex Dimerocerataceae) which is included in the suborder Tornoceratina.

Saunders et al[2] includes the Cheiloceratidae in the suborder Tornoceratina along with the Maenioceratidae, Tornoceratidae, Sinotitidae, Posttornoceratidae, Sporadoceratidae, and Dimeroceratidae; without the use of a superfamily.
