Conus fragilissimus, common name the fragile geography cone, is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.{{WRMS species|428127|Conus fragilissimus Petuch, 1979|WoRMS (2010)|25 September 2011}}

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.
