Palaina edwardi, also known as Edward's staircase snail, is a species of staircase snail that is endemic to Australia's Lord Howe Island in the Tasman Sea.

The globose pupiform shell of adult snails is 3–3.1 mm in height, with a diameter of 1.7 mm, with deeply impressed sutures.

It is pale golden-brown in colour, with a white peripheral band on the final whorl and radial streak above the aperture.

The circular aperture has a strongly reflected lip and an operculum.

[2] The snail is rare and only found on the southern mountains of the island.
