Vasidae, common name the vase snails or vase shells, are a taxonomic family of large predatory sea snails, marine gastropod mollusks within the superfamily Turbinelloidea. Before 2024 it was considered as a subfamily of the Turbinellidae. Despite their historical inclusion in Turbinelloidea, they have been found by phylogenetic analysis to form a well-supported clade with Buccinoidea, while there is less support for a buccinoid clade to the exclusion of Vasidae, leading to the suggestion of including Vasidae in Buccinoidea.

Shell description
The radula on the lingual membrane occur in three series, the central recurved, toothed at the tip, the lateral not versatile; the central tooth is broad, few-toothed; the lateral teeth are narrow, strong, with a single large denticle. The mantle is enclosed, with a straight siphon. The operculum is ovate, acute, with the nucleus apical. The shell is more or less turbinate, with plaits on the middle of the columella. Shells of species in this subfamily are fairly large, very thick, and heavy. The shells have low spires and have plaits on the columella.
