Pyramidella dolabrata, common name the "giant Atlantic pyram", is a somewhat variable species of small to medium-sized (max size 36 mm) sea snail, a marine gastropod mollusk in the (mostly minute) family Pyramidellidae, the pyram snails.

The white shell is conical, turreted, polished, elongated, slightly transparent.

The pointed spire is composed of from ten to twelve distinct, smooth, slightly convex whorls.

The ovate aperture is subrotund at its base, and generally marked within, with very prominent ridges continued upon some specimens even to the edge of the sharp outer lip.
