Gigahomalopoma luridum, with the common names Dall's dwarf turban or dark dwarf-turban snail, is a species of small sea snail with calcareous opercula, a marine gastropod mollusk in the family Colloniidae.

These are slightly convex, the last decidedly deflected toward the aperture, encircled by about fifteen subequal spiral lirae, separated by interstices about as wide as the ridges.

The incremental striae are generally strongly developed, causing the liree to appear nodose or somewhat irregular, and the interstices to appear pitted.

The rounded oval operculum is nearly smooth and slightly concave in the middle.

[4] This species occurs in abundant numbers in the Pacific Ocean under rocks and an shale at low tide from Sitka, Alaska to Northern Baja California, Mexico.
