Turbo argyrostomus, common name the silver-mouthed turban, is a species of sea snail, marine gastropod mollusk in the family Turbinidae.

The color pattern of the shell is cream, irregularly maculated with greenish and brown, and broken lines of black.

The body whorl contains about thirteen lirae, which are generally wider than their interstices, and of which the subcoronal and one or two median ones are more prominent.

The outer surface is convex, with coarse obtuse granules, which are largest upon the higher part, nearly surrounded by a marginal series of fine oblique wrinkles.

[1][2] This species and its subspecies are distributed in the Red Sea and in the tropical Indo-West Pacific off Aldabra, Chagos, Madagascar, the Mascarene Basin, Mozambique and Tanzania; off Andaman Islands and Nicobar Islands, East India, the Philippines; off Australia (Northern Territory, Queensland, Western Australia).
