Turbinidae, common name the turban snails, are a taxonomic family of small to large sea snails, marine gastropod molluscs in the clade Vetigastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

Previously these snails were classified in the subclass Prosobranchia, in the order Archaeogastropoda in the superfamily Trochacea. Trochaecea is now a synonym for the superfamily Trochoidea.
In life, all the snails in this family have a strong, thick calcareous operculum, or "door" to their shell. This readily distinguishes them from the Trochidae or top snails, which have a corneous operculum, but which are otherwise somewhat similar.
The common name "turban snail" is a reference to the wrapped cloth headgear known as a turban. This is potentially a little misleading, as the Latin name Turbinidae does not mean turban shells, but instead is based on the genus name Turbo, which is the Latin word for a spinning top, a child's toy. For a similar derivation see the word turbine.
