Triviidae is ataxonomicfamily of smallsea snails,marinegastropodmolluscs in the superfamily Cypraeoidea of the orderLittorinimorpha.^[1]

The following subfamilies were recognized in thetaxonomy of Bouchet & Rocroi in 2005:

• EratoinaeGill, 1871
  • tribeEratoiniGill, 1871
  • † tribeJohnstrupiiniSchilder, 1939
  • † tribeEratotriviiniSchilder, 1936
• TriviinaeTroschel, 1863: represented as TriviidaeTroschel, 1863

In theTaxonomy of the Gastropoda (Bouchet et al., 2017) Eratoinae is now recognized as the familyEratoidae and Triviinae is considered an alternate representation of Triviidae.
