Bankivia fasciata, common name the banded kelp shell, is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.

It is polished and shining, white, creamy or pink, with spiral bands of pink, purplish-red or purplish-brown, or narrow oblique zigzag stripes of pinkish-brown, usually with a narrow subsutural fascia of dark or pinkish.

The about 9 whorls are, very slightly convex, and a trifle impressed below the sutures.

The base of the shell shows a few concentric, separated, impressed lines.

The sinuous columella is arcuate above and narrowly reflexed, obliquely truncate below.
