Rhytididae is a taxonomic family of medium-sized predatory air-breathing land snails, carnivorous terrestrial pulmonate gastropod molluscs in the superfamily Rhytidoidea. This family has no subfamilies. In this family, the number of haploid chromosomes lies between 26 and 35.

This family of land snails has a range which extends from South Africa to New Guinea, some of the higher South Pacific islands, New Zealand and Australia. The New Zealand genera include Delos, Delouagapia, Paryphanta, Powelliphanta, Rhytida, Wainuia and Schizoglossa. These, however, probably do not form a monophyletic group, as indicated by their differences in their size, shape and radular morphology.
