Stenanthemum radiatum is a species of flowering plant in the family Rhamnaceae and is endemic to a restricted part of the southwest of Western Australia.

Stenanthemum radiatum is a spreading shrub that typically grows to a height of 10–30 cm (3.9–11.8 in), its young stems sparsely covered with white star-shaped and simple hairs.

[2][3] Stenanthemum radiatum was first formally described in 2007 by Barbara Lynette Rye in the journal Nuytsia from specimens collected in 1998 in the Burma Road Nature Reserve.

[3][4] The specific epithet (radiatum) means "with spokes" or "radiating", referring to the arrangement of the leaves around the flower clusters.

[2][3][5] Stenanthemum radiatum is listed as "Priority Two" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[5] meaning that it is poorly known and from only one or a few locations.
