Acochlidiacea, common name acochlidians, are a taxonomic clade of very unusual sea snails and sea and freshwater slugs, aquatic gastropod mollusks within the large clade Heterobranchia. Acochlidia is a variant spelling.

Schematic drawing of dorsal view of Pseudunela cornuta shows some characteristics of acochlidians, but characteristics of other acochlidians differ greatly:
f – foot
hb – heart bulb
lt – labial tentacle
rh – rhinophore
vh – visceral hump.
