The Capulidae, the cap snails or cap shells, are a taxonomic family of limpet-like sea snails, marine gastropod molluscs.

Capulidae is the only family in the superfamily Capuloidea. Capulidae is assigned to the paraphyletic order Littorinimorpha, but is more closely related to neogastropods than some other littorinimorphs as it is a member of the clade Latrogastropoda.

The name Trichotropidae was previously used for this family, but this name is invalid, as it is a junior synonym.
