Cominella is a genus of carnivorous sea snails, a marine gastropod mollusc in the family Cominellidae.

Cominella is a genus of medium-sized buccinoid marine snails. All species are carnivores.
Many extant species are endemic to coastal waters off of New Zealand and Australia (including Norfolk Island). There is a rich fossil record in New Zealand. Species are common within the intertidal and subtidal zone.
Cominella is currently classified within the family Buccinidae, although it has also been classified within the alternative families Buccinulidae and Cominellidae.
Ancestors of Cominella species in Australia likely migrated from New Zealand via long-distance egg rafting, despite taxa exhibiting direct development. Cominella is closely related to the genus Pareuthria.
Species and subspecies (indented) in the genus Cominella include:
