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

It is a bushy shrub with profuse cream, yellow or greenish flowers and overlapping leaves on the youngest shoots.

Melaleuca densa grows to a height of about 2–3 m (7–10 ft) and has fibrous, grey or almost white bark.

[4][5] The reason Brown chose the specific epithet (densa) is not known but it is from the Latin densus, meaning "dense", and may refer to the density of the leaves or of the flowers in the inflorescence.

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