Conus cacao 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 22 mm and 55 mm.
This species occurs in the Atlantic Ocean off Senegal, and in the Mediterranean Sea.
