Pomaderris rotundifolia is a species of flowering plant in the family Rhamnaceae and is endemic to Western Australia.

It is an upright, spreading shrub that typically grows to a height of 0.1–1.5 m (3.9 in – 4 ft 11.1 in), its branchlets covered with star-shaped hairs.

In most respects it is similar to other species of Pomaderris occurring in Western Australia but has more prominent bracts, shorter pedicels and well-developed petals.

[7] Pomaderris rotundifolia is found in the south of Western Australia in the Esperance Plains and Mallee biogeographic regions of the state.

It is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
