Quoya cuneata is a flowering plant in the mint family Lamiaceae and is endemic to the south-west of Western Australia.

Quoya cuneata is a spreading shrub which grows to a height of 0.6–3.5 m (2–10 ft) and which has its branches densely covered with pale white or brownish hairs.

The five sepals are 5–6 mm (0.20–0.24 in) long, with the egg-shaped lobes in two groups, five in one, two in the other with the upper three-lobed "lip" larger than the lower one.

Flowering occurs from August to November or December and is followed by the fruit which is oval-shaped to almost spherical, 2–3 mm (0.08–0.1 in) in diameter with the sepals remaining attached.

[2] This species was first formally described in 1828 by Charles Gaudichaud-Beaupré from a specimen collected in Shark Bay during the Bougainville expedition in the ships l'Uranie and la Physicienne from 1817 to 1820.
