Melaleuca plumea is a shrub in the myrtle family, Myrtaceae, and is endemic to the south of Western Australia.

It is a widely spreading, densely foliaged shrub which produces masses of deep pink flowers in spring and early summer.

[4][5] The specific epithet (plumea) is from the Latin plumeus meaning "downy"[6] referring to the woolly parts of the flowers.

[2] This melaleuca occurs in and between the Salmon Gums, Scaddan and Mount Beaumont districts[2] in the Esperance Plains and Mallee biogeographic regions growing in sand or clay, on dune slopes and near salt lakes and river flats.

[7] Melaleuca plumea is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.
