Conus berdulinus 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 48 mm and 100 mm.
This species occurs in the Indian Ocean from Natal, South Africa to Mozambique and the Mascarenes, Somalia; off Southern Oman and Southern India; in the Pacific Ocean off Midway and Hawaii; in the South China Sea and off the Philippines.
