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

The flowers are arranged in head-like, condensed cymes on the ends of branchlets.

[6][7] In 1863, George Bentham changed the name to Spyridium oligocephalum in Flora Australiensis.

[9] Spyridium oligocephalum grows in sandy soil on sandplains in the Esperance Plains and Jarrah Forest bioregions of south-western Western Australia.

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