Steromphala divaricata, common name the divaricate gibbula, is a species of small sea snail, known as top snails or top shells, marine gastropod molluscs in the family Trochidae, the top snails.

The conoidal shell is imperforate or narrowly perforate.

It is longitudinally marked with rose-red lines, often oblique or broken into square dots.

The six whorls are encircled by numerous lirulae, the upper ones flattened.

The outer lip is bevelled to an edge, very thick and smooth within.
