Commersonia densiflora is a species of flowering plant in the family Malvaceae and endemic to the south-west of Western Australia.

It is a dense, low-growing shrub with pinnate, elliptic to narrowly oblong, prominently veined leaves, and white flowers in clusters of 100 or more.

Flowering occurs from August to November and the fruit is a hairy capsule 4–5 mm (0.16–0.20 in) in diameter.

[3][4] In 1876, Ferdinand von Mueller transferred the species to Commersonia as C. densiflora in his Fragmenta Phytographiae Australiae.

[6] Commersonia densiflora grows in shrubland and woodland between Mullewa, Kalbarri and Shark Bay in the drier parts of the Avon Wheatbelt, Geraldton Sandplains, Swan Coastal Plain and Yalgoo bioregions of south-western Western Australia.
