Turricula turriplana is a species of sea snail, a marine gastropod mollusk in the family Clavatulidae.

The first two whorls are smooth, rounded, forming a somewhat prominent white papillary apex.

The other whorls are slopingly convex, slightly impressed below the suture, spirally faintly grooved, obliquely obscurely plicated.

It is convex above, attenuated towards the base, scarcely rostrate, nearly smooth with spiral grooves (only visible with a lens) that are irregular and broken up.

The outer lip is sharp, with a broad posterior sinus, situated between the angle and the suture.
