Conus lamberti 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 70 mm and 114 mm. The smooth shell is orange-brown, with large subtriangular white patches, mostly arranged so as to indicate three broad bands.
