Jacksonia lehmannii is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia.

It is an erect to prostrate or spreading, spindly shrub with greyish-green branches, sharply-pointed side branches, its leaves reduced to scales leaves, yellowish-orange flowers with orange-red markings, and woody, hairy pods.

[2][3] Jacksonia lehmannii was first formally described in 1844 by Carl Meissner in Lehmann's Plantae Preissianae from specimens collected by James Drummond near the Canning River in 1839.

[6] This species of Jacksonia grows in shrubland or woodland in sandplains on sand over laterite in disjunct areas near Eneabba, between Maida Vale and Pinjarra, and south of Capel in the Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia.

[2][3] Jacksonia lehmannii is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
