Neomphalina is a major taxonomic grouping of sea snails, vent-endemic marine gastropod mollusks that form a very ancient lineage, going back to the Palaeozoic era. 
Neomphaloidea was regarded for a long time as belonging within the clade Vetigastropoda. Molecular phylogeny showed however that it belongs in its own clade, the Neomphalina, and that this clade is basal to the Vetigastropoda. The Neomphalina is a monophyletic clade, with uncertain relations among the gastropods.   
The clade Neomphalina has the largest
radiation in in situ hydrothermal vent habitats.
