Choristella is a genus of sea snails, marine gastropod mollusks in the family Choristellidae.

==Description== (Original description by Bush) This genus is proposed for species of small shells of few convex whorls forming a flattened, little elevated spire with a minute, scarcely raised, nuclear whorl and a large body whorl. The suture is very deep, and somewhat channeled. The umbilicus is small, round, deep, showing some of the whorls with rounded walls. The oblique aperture is nearly circular. The peristome is simple, continuous, slightly attached to the body whorl, and reflected over the umbilicus. The operculum of the type species is thin, roundly ovate. it has a delicate horn color, of few abruptly enlarging whorls indistinctly defined by a spiral thread and showing sinuous transverse lines of growth. The nucleus is slightly excentric.
