Styphelia sieberi, commonly known as prickly beard-heath,[2] is a species of flowering plant in the heath family Ericaceae and is endemic to south-eastern continental Australia.

It is an erect, densely-branched shrub with oblong to more or less egg-shaped leaves with the narrower end towards the base, and white, tube-shaped flowers arranged singly in upper leaf axils.

[2][3][4] This species was first formally described in 1810 by Robert Brown who gave it the name Leucopogon juniperinus in his Prodromus Florae Novae Hollandiae et Insulae Van Diemen.

[5][6] In 2020, Michael Hislop, Darren Crayn and Caroline Puente-Lelievre transferred the species to Styphelia as S. sieberi in Australian Systematic Botany.

[7] Prickly beard-heath grows in forest and open shrubland on the coast and nearby tablelands of south-eastern Queensland, New South Wales and east of the Mitchell River in Victoria.
