Crassopleura maravignae is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.

The fusiform shell is yellowish- or reddish-brown, sometimes partitioned over the spire whorls by a spiral line separating darker and lighter areas.

The body whorl has an inflated profile, not narrowing at all around the siphonal canal; with axial ribs attenuated towards the base.

The aperture is distinctly thickened behind the outer lip in adults although without forming a delimited rib or varix.

[2][3] This species occurs in the Mediterranean Sea off Spain, Italy and Greece; in the Eastern Atlantic Ocean off the Azores, from Galicia to Morocco and Senegal, off the Canary Islands.
