Trochoidea is a superfamily of small to very large sea snails which have an operculum and have nacre as the inner shell layer. These are marine gastropod mollusks in the subclass Orthogastropoda and the superorder Vetigastropoda. The families within this superfamily are the Trochidae and the Turbinidae, the top snails and the turban snails.
Note that this is not the same as the pulmonate land snail genus which is spelled the same way, for that see Trochoidea (genus).
