Neocomitidae is a family of Lower Cretaceous ammonitids comprising genera with strongly ribbed evolute (all whorls exposed) to smooth, fairly involute (inner whorls mostly hidden) shells.[1]

In the 1957 description of the family[2] Neocomitidae was regarded as the subfamily Neocomitinae within the Berriasellidae, a family within the Perisphinctoidea that ranged from the Late Jurassic into the Early Cretaceous. In a more recent treatment [3] berriaselids are regarded as a subfamily within the Neocomitidae.

Current opinion differers from the 1967 placement of Neocomitidae in the Perisphinctoidea[2] but rather includes it in the superfamily Endemoceratoidea.[4][5]
