Volvarina is a genus of small to very small sea snails, marine gastropod molluscs in the family Marginellidae, the margin shells.

Larger species with a strong callus are classified under Prunum, while the slender species with a thin callus are classified under Volvarina.

Many species with characteristics that fall between the two extremes are ambiguous.

[1] Volvarina is paraphyletic in relation to Prunum and Hyalina.

The genus is cosmopolitan with most species in warm and temperate seas.
