Calliostoma occidentale, common name the boreal topsnail, is a species of sea snail, a marine gastropod mollusk in the family Calliostomatidae.

The shell is rather small, thin, imperforate, and opalescent with a shining surface.

It is strongly sculptured above with smooth, yellowish spiral ribs, narrower than their interstices, numbering 3 or 4 on each of the 7 to 8 whorls.

The base of the shell is nearly flat, with a few ribs around the axis and at the periphery, otherwise it is smooth.

It occurs in European waters, the Northwest Atlantic Ocean, Greenland, Scandinavia and in the Barents Sea at depths between 18 m and 1800 m.
