Chilodontidae is a taxonomic family of mostly small deepwater sea snails, marine gastropod molluscs in the clade Vetigastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

Taxonomy The family was previously in the superfamily Neritoidea in the order Neritopsina and the superorder Neritaemorphi.

2005 taxonomy This family consists of three following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005): Chilodontainae Wenz, 1938 Calliotropinae Hickman & McLean, 1990 Cataeginae McLean & Quinn, 1987

2007 taxonomy A molecular phylogeny-based taxonomy of the Seguenzioidea was published by Kano (2007).Kano Y. (2007). "Vetigastropod phylogeny and a new concept of Seguenzioidea: independent evolution of copulatory organs in the deep-sea habitats". Zoologica Scripta 37(1): 1–21.

It was proposed to rename the family Chilodontidae Wenz, 1938 as "Chilodontaidae" because it was a homonym of the fish family "Chilodontidae" Eigenmann, 1912, but a 2024 ICZN ruling instead changed the name of the fish family to Chilodidae, so the gastropod family is still to be kept as Chilodontidae.Opinion 2502 (Case 3555) – Chilodontidae Bronn, 1859 (Ciliophora), Chilodontinae Eigenmann, 1910 (Pisces, Characiformes) and Chilodontinae Wenz, 1938 (Mollusca, Gastropoda): homonymy between family-group names resolved. The Bulletin of Zoological Nomenclature 81(1): 133-136 (31 December 2024) doi:10.21805/bzn.v81.a025

The subfamilies Calliotropinae Hickman & McLean, 1990 and Cataeginae McLean & Quinn, 1987 were raised to family levels as the Calliotropidae and the Cataegidae.
