Sphaerolobium fornicatum is a species of flowering plant in the family Fabaceae and is endemic to the far south-west of Western Australia.

It is a leafless shrub that typically grows to a height of 0.1–1 m (3.9 in – 3 ft 3.4 in) and has yellow or orange and red flowers from October to January.

[2][3] It was first formally described in 1837 by George Bentham in Stephan Endlicher's Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel from specimens collected near King George Sound.

[4][5] The specific epithet (fornicatum) means "arched", referring to the curved keel.

[6] Sphaerolobium fornicatum occurs in the Jarrah Forest and Warren bioregions of far south-western Western Australia and is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
