Tegula quadricostata is a species of sea snail, a marine gastropod mollusk in the family Tegulidae.

The thick, solid, umbilicate shell has a conical shape and has a blackish color.

The base of the shell shows 3 or 4 separated smaller beaded ribs, the broad interstices both above and below densely, finely spirally striate.

The umbilicus is surrounded by a white callus, bearing inside a strong spiral rib which terminates in a denticle about the middle of the columella.
