Littorinimorpha is a large clade of gastropods within Hypsogastropoda consisting primarily of marine species, but also aquatic and terrestrial species as well.[1]

Previously the Linnaean taxonomy in the taxonomy of the Gastropoda by Ponder & Lindberg (1997) was ranked like this: subclass Orthogastropoda, superorder Caenogastropoda, order Sorbeoconcha, suborder Hypsogastropoda, infraorder Littorinimorpha.

The clade Littorinimorpha contains many of the gastropod families formerly placed in the order Mesogastropoda, as introduced by J. Thiele in his work from 1921.[2] Evidence for this group being monophyletic is scanty. E.E.Strong [3] has suggested using only Neogastropoda as a clade within the clade Hypsogastropoda and to include the unresolved superfamilies of the Hypsogastropoda within the Littorinimorpha.[4]
