Conus austroviola is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.
Like all species within the genus Conus, these snails are predatory and venomous. They are capable of "stinging" humans, therefore live ones should be handled carefully or not at all.
The size of the shell varies between 23 mm and 57 mm.
This marine species is endemic to Australia and occurs off the Northern Territory, Queensland and Western Australia.
