Semilaoma laevis, also known as the smooth pinhead snail, is a tiny species of land snail that is endemic to Australia's Lord Howe Island in the Tasman Sea.

[2] The depressedly turbinate shell of the mature snail is 0.7–0.8 mm in height, with a diameter of 1.2–1.3 mm, and a low spire.

The sutures are impressed, with closely-spaced radial ribs.

It has a roundly lunate aperture, and a narrowly open umbilicus.
