Melaleuca deanei, commonly known as Deane's paperbark, is a plant in the myrtle family, Myrtaceae and is endemic to New South Wales in Australia.

[2][3][4][5] Melaleuca deanei was first formally described in 1886 by Ferdinand von Mueller in Proceedings of the Linnean Society of New South Wales from a specimen collected by Henry Deane "on the northern side of the Lane Cove River, occupying sandy ground on the ridges".

[6][7] The specific epithet (deanei) is "in honour of Henry Deane (1847–1924), a railways engineer who also made many contributions to Australian botany, especially in the fields of eucalyptology and palaeobotany and who collected the type material of this species".

[3][4] It is difficult to count the number of individual plants of M. deanei because they tend to reproduce by suckering, clones are therefore common and observations of seedlings are rare.

[4] Whilst some of the populations are in national parks or reserves, the threats include habitat disturbance, clearing, altered fire regimes, trail maintenance and weed encroachment.
