Raphitoma atropurpurea is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.

The monochrome dark brown shell has a somewhat elongated, fusiform shape.

The shell contains 10 convex whorls, separated by a rather impressed suture.

The whorls show narrow, close, prominent ribs intersected by decurrent, narrow, prominent, regular and continual striae, forming a regular reticulation.

[2] This marine species occurs in the Mediterranean Sea off Southern France and Corsica.
