Stenanthemum nanum is a species of flowering plant in the family Rhamnaceae and is endemic to the south-west of Western Australia.

It is a prostrate shrub with hairy young stems, broadly egg-shaped leaves with the narrower end towards the base, and densely silvery-hairy heads of white or cream-coloured flowers.

Stenanthemum nanum is a spreading, more or less prostrate shrub that typically grows to a height of up to 10 cm (3.9 in), its young stems covered with straight and star-shaped hairs.

[2][3] Stenanthemum nanum was first formally described in 1995 by Barbara Lynette Rye in the journal Nuytsia from specimens collected by Alex George, 50 km (31 mi) south-east of Perth in 1965.

[2][3][5] Stenanthemum nanum is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions[5]
