Vespericola is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Polygyridae.
These snails are found along the Pacific Coast of North America, from southern Alaska and British Columbia to California.
The shells of these small to medium, globose or depressed globose snails are usually some shade of brown, sometimes without apertural teeth and sometimes with a single tooth on the parietal wall. Small periostracal hairs may be observed on the shell surface of many specimens, but the shells otherwise resemble those of Praticolella or Mesodon.
According to Pilsbry (1940), Vespericola "differs from all other Polygyridae by the possession of a well-developed though rather short verge, and by the peculiar shape of the epiphallus".
Species within the genus Vespericola include:
