Olivella, the dwarf olives, is a genus of predatory marine gastropods similar to the olives of the family Olividae, but with a more produced spire and a large, thin, horny operculum (Oldroyd 1927).

Characters (from Oldroyd 1927): Shell polished, small; spire produced, acute, suture canaliculated; aperture narrow behind, enlarged anteriorly; columella plicated in front, callous posteriorly. Operculum horny, thin, half ovate, with apical nucleus.
