Conostephium preissii is a species of flowering plant in the family Ericaceae and is endemic to the southwest of Western Australia.

It is an erect shrub with many stems, egg-shaped to oblong leaves and white and purplish to reddish-pink flowers.

Its leaves are egg-shaped with the narrower end towards the base to oblong and 13–19 mm (0.51–0.75 in) long with the edges rolled slightly downwards and often a small point on the tip.

[6] This conostephium grows in heath on sandplains and winter-wet flats mainly on the coastal plain from near Eneabba to near Harvey, but also east of the Darling Scarp and further inland, in the Avon Wheatbelt, Coolgardie, Geraldton Sandplains, Jarrah Forest, Mallee and Swan Coastal Plain bioregions of south-western Western Australia.

[3][7] Conostephium preissii is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
