Conus fergusoni, common name the Ferguson's cone, 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 an adult shell varies between 60 mm and 150 mm. The heavy shell has a slightly channeled spire. The white shell is lightly striolate transversely and is covered under a brown epidermis.
This species occurs in the Pacific Ocean off the Galapagos Islands and from the Gulf of California to Peru.
