Anatoma crispata is a species of small sea snail, a marine gastropod mollusk or micromollusk in the family Anatomidae.

The globose, pearly white shell slopes toward the periphery.

The sculpture consists of numerous fine, curved, longitudinal ribs, interrupted by the slit fasciole, closer on the base, intersected by minute spiral striae in the interstices.

It occurs in circumarctic waters (Greenland, Canada, Baffin Island, Queen Elisabeth Islands, Labrador), in European waters, the Mediterranean Sea, in the Atlantic Ocean off the Azores, Cape Verde, Angola; in the Northwest Atlantic Ocean (Florida, the Bahamas), in the West Indies, in the Pacific Ocean off California and Japan.

This species has been cited from multiple localities throughout the North Atlantic, but most records are inaccurate due to confusion with Anatoma aspera (mostly), A. tenuisculpta and A. orbiculata.
