Powelliphanta gilliesi compta is a rare terrestrial mollusc in the family Rhytididae, endemic to the South Island of New Zealand. It is found only in the West Nelson area.

Shell coloration is golden to sienna-brown with the dorsal surface and periphery spirally lined in dark-brown and with a secondary series in light green. The base is largely plain but with a slight deepening of tone, accompanied by crowded faint lines, around the umbilicus. The parietal callus (thickened calcareous deposit on the upper part of the inside wall of the aperture) is dark pinkish-grey, with a few scattered granulations within.

Major diameter is up to 48 mm, and height up to 28 mm.

Powelliphanta gilliesi compta is classified by the New Zealand Department of Conservation as being Nationally Vulnerable.
