Commersonia borealis is a species of flowering plant in the family Malvaceae and is endemic to the southwest of Western Australia.

It is a low growing, spreading shrub with egg-shaped to oblong leaves, and white, yellow and cream-coloured flowers.

The edges of the leaves have rounded lobes and are rolled under, the lower surface densely covered with white, star-shaped hairs.

Flowering occurs from July to November and the fruit is a capsule 5–9 mm (0.20–0.35 in) long and densely-covered with white, star-shaped hairs.

[6][8] Commersonia borealis grows in limy sand or loam over limestone in near-coastal shrubland, open woodland or heath between Shark Bay and Seabird north of Perth and on Dirk Hartog Island in the Geraldton Sandplains, Swan Coastal Plain and Yalgoo bioregions of south-western Western Australia.
