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

Stenanthemum poicilum is a twiggy, erect or low-lying shrub that typically grows to a height of 15–50 cm (5.9–19.7 in), its young stems hairy.

[2][3] Stenanthemum poicilum was first formally described in 1995 by Barbara Lynette Rye in the journal Nuytsia from specimens collected in 1992.

[2] This species grows in heath and shrubland near Canna and on the Bremer Range in the Avon Wheatbelt and Yalgoo bioregions of south-western Western Australia.

[2][3][5] Stenanthemum poicilum is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[5] meaning that it is poorly known and known from only a few locations but is not under imminent threat.
