Crassispira chazaliei is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae.

It contains 11 whorls, of which the apical are smooth, shining, apparently carinate centrally, but the type specimen is a little worn and imperfect in this particular.

The lower whorls are suturally impressed just below the sutures, at the summit of each whorl, once spirally acutely keeled, the remaining portion being rather ventricose, longitudinally obliquely multicostate, crossed by, on the four penultimate whorls, three to five spiral revolving lines, gemmulate at the several points of junction with the ribs.

The body whorl possesses fourteen such lirae, with over twenty closely grained ribs.

The outer lip is not effuse, columellar nearly straight, the sinus shallow, but well expressed.
