Calytrix purpurea is a species of flowering plant in the myrtle family Myrtaceae and is endemic to the south-west of Western Australia.

Calytrix purpurea is a spreading shrub that typically grows to a height of 30–60 cm (12–24 in).

[2][3] This species was first formally described in 1859 by Ferdinand von Mueller who gave it the name Lhotskya purpurea in his Fragmenta Phytographiae Australiae from specimens collected near Champion Bay by Augustus Oldfield.

[7] Calytrix purpurea grows on sand plains and sand dunes in coastal heath and in Melaleuca scrub in the Kalbarri district and the Champion Bay district in the Avon Wheatbelt and Geraldton Sandplains bioregions in the south-west of Western Australia.

Calytrix purpurea is listed as "Priority Two" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[3] meaning that it is poorly known and from only one or a few locations.
