Pinufiidae is a family of sea slugs, specifically nudibranchs, marine gastropod molluscs in the superfamily Fionoidea.

In Korshunova et al. (2025), Pinufiidae was not recognized as a family but as a subgroup or 'subfamily' of the family Trinchesiidae. This is due to the type genus Pinufius bearing close relations the trinchesiid Phestilla.
