Steromphala adansonii is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.^[2]

The height of the shell attains 12 mm, its diameter 10½ mm.

The narrowly umbilicate shell has a conical shape. Its color is maroon or deep brown, with longitudinal undulating flames of white, continuous or interrupted into spots on the base. The elevated spire is conoidal and contains 6 to 7convex whorls, traversed by numerous spiral striae. The large body whorl is dilated and subangulate at the periphery. The base of the shell is convex, concentrically finely lirate, each ridge divided by a central impressed line. The sutures are deeply impressed. The aperture is subquadrangular. The columella is straight or a little projecting in the middle. The deep umbilicus is very narrow, bounded by a carina.^[3]

This species occurs in the Mediterranean Sea, the Adriatic Sea and the Black Sea.
