Profundiconus neotorquatus 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 length of the shell varies between 50 mm and 111 mm.
