Gibbula capensis is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.

The narrowly umbilicated shell has a conoid-depressed shape with 5 whorls.

The first whorl is roseate, eroded, the following convex above, depressed beneath, whitish or rosy, flammulated with brownish-violet radiating maculations, obliquely striate and spirally lirate.

The body whorl is dilated, subangulate above, depresso-carinated at the periphery, convex beneath and ornamented with 9 concentric reddish lirae.

The columella is arcuate, denticulate at base, slightly calloused above, almost covering the umbilicus.
