Styphelia tamminensis is a species of flowering plant in the heath family Ericaceae and is endemic to the southwest of Western Australia.

It is a slender shrub with many branches, overlapping triangular to egg-shaped leaves and white, tube-shaped flower arranged singly in upper leaf axils.

The flowers are arranged singly in upper leaf axils with lance-shaped bracts and broadly egg-shaped bracteoles about 1.5 mm (0.059 in) long.

[2] This species was first formally described in 1904 by Ernst Georg Pritzel who gave it the name Leucopogon tamminensis in Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie from a specimen found on sand-dunes near Tammin.

[7] Styphelia tamminensis is listed as "Priority Two" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[7] meaning that it is poorly known and from only one or a few locations.
