Triviella, common name the smooth pearl cowries, is a genus of small sea snails, marine gastropod molluscs in the family Triviidae, the trivias.

[1] The genus *Triviella* (formerly considered a subgenus of *Trivia*) includes several species that are highly similar and often require microscopic examination of the live animal for accurate species-level identification.

The shells of smooth pearl cowrie species are inflated and globular, with a thickened labrum (outer lip of the aperture) that features well-developed denticles.

These denticles often extend as transverse ridges around the outer lip, occasionally reaching the lower lateral part of the dorsum.
