Bellastraea aurea, common name the golden small star, is a species of sea snail, a marine gastropod mollusk in the family Turbinidae, the turban snails.

The small, solid, imperforate shell has a depressed-conic shape.

The whorls are spirally lirate, the lirae below rather coarse, beaded, above finer, cutting the folds more or less into granules.

The body whorl generally descends toward the aperture, and is compressed toward the periphery, which is subangular except in large specimens.

The columellar callus is dilated over the umbilical region, and excavated there, and with an indistinct denticle near its base.
