Acochlidiidae are a taxonomic family of shell-less freshwater gastropods (one of them Palliohedyle weberi lives in brackish water), aquatic gastropod mollusks within the clade Acochlidiacea.
Acochlidiidae was classified as the only family within the superfamily Acochlidioidea Küthe, 1935 in the taxonomy of Bouchet & Rocroi (2005). Palliohedylidae was in turn classified as the only family within the superfamily Palliohedyloidea.
Schrödl & Neusser (2010) redefined the taxonomy of Acochlidiacea in 2010, placing the family Acochlidiidae in the clade Hedylopsacea.
According to Schrödl & Neusser (2010), there are three genera in the family Acochlidiidae:
Acochlidium Strubell, 1892
Palliohedyle Rankin, 1979
Strubellia Odhner, 1937
