Spyridium tricolor is a species of flowering plant in the family Rhamnaceae and is endemic to southern continental Australia.

[2][3] Spyridium tricolor was first formally described in 1993 by William Robert Barker and Barbara Lynette Rye in the Journal of the Adelaide Botanic Gardens from specimens collected by Paul G. Wilson, near Point Dover on the Great Australian Bight in 1967.

[2][4] The specific epithet (tricolor) means "three-coloured", referring to the leaves, pale to mid-green on the upper surface, rust-coloured at first, later grey on the lower surface.

[2] This spyridium grows in sandy soil with limestone, often in mallee shrubland between Cape Arid National Park and Eyre in Western Australia, and disjunctly near Ceduna in South Australia.

[2][3][5] Spyridium tricolor is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
