Profundiconus lani 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 Profundiconus, these cone 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 41 mm and 54 mm.
This marine species occurs off Taiwan, the Philippines, the Solomon Islands, the Loyalty Islands and New Caledonia; in the South China Sea.
