Stenodrillia horrenda is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.

(Original description) The very coarse and strong, long, narrow shell has with a concave conical base.

They are parted by broad open furrows, which run obliquely to the left and more or less continuously down the spire.

The outer lip is immensely but remotely thickened outside by the last rib, from which it is bevelled off to a narrow edge.

The U-shaped sinus is deep, broad, and strong, close up to the suture but parted from it by a big triangular shelf.
