Xerocrassa is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod molluscs in the subfamily Helicellinae of the family Geomitridae.

Some species of Xerocrassa are instead considered to belong to the subgenus Xerocrassa, within the genus Trochoidea; in those cases the species are listed under the generic name Trochoidea. However, for other authors both taxa are not closely related being different genera.

• Xerocrassa (Amandana) Fagot, 1891
