Styphelia subulata is a species of flowering plant in the heath family Ericaceae and is endemic to the south-west of Western Australia.

The flowers are usually arranged singly or in pairs in leaf axils on a very short peduncle, with very small bracts and bracteoles less than half the length of the sepals.

[2] This species was first formally described in 1864 by Ferdinand von Mueller who gave it the name Leucopogon subulatus in his Fragmenta Phytographiae Australiae, from specimens collected near the Great Australian Bight by George Maxwell.

[3][4] In 2020, Michael Hislop, Darren Crayn and Caroline Puente-Lelievre transferred the species to Styphelia as S. subulata in Australian Systematic Botany.

[5] Styphelia subulata is found in the Avon Wheatbelt, Coolgardie, Esperance Plains and Mallee bioregions of south-western Western Australia.
