Leucopogon tamariscinus is a species of flowering plant in the heath family Ericaceae and is endemic to the south of Western Australia.

It is an erect shrub with egg-shaped or lance-shaped leaves and white, tube-shaped flowers arranged in dense spikes on the ends of branches.

[2][3] Leucopogon tamariscinus was first formally described in 1810 by Robert Brown in his Prodromus Florae Novae Hollandiae et Insulae Van Diemen.

[6] This leucopogon grows on sandplains and on laterite ridges in the Avon Wheatbelt, Esperance Plains, Jarrah Forest and Mallee bioregions of southern Western Australia.

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