Melaleuca rosea (A.S.George) Craven & R.D.Edwards Calothamnus roseus is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia.

Flowering occurs from September to November and is followed by fruits which are smooth, woody capsules, 13–16 millimetres (0.5–0.6 in) long.

[2] Calothamnus roseus was first formally described in 2010 by Alex George in Nuytsia from a specimen found near Ravensthorpe.

[2] Calothamnus roseus occurs near Ravensthorpe in the Esperance Plains biogeographic region,[4] where it grows in rocky soil derived from quartzite.
