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

It is one of the smallest melaleucas and is distinguished by its warty, hairy leaves, heads of pinkish flowers in late winter to spring and its spherical fruiting clusters.

Flowering occurs from July to October and is followed by fruit which are woody capsules, 2.5–3.0 millimetres (0.098–0.12 in) long, packed tightly together in spherical or oblong clusters.

[2][3] Melaleuca tinkeri was first formally described in 1999 by Lyndley Craven in Australian Systematic Botany from a specimen collected 7 km (4 mi) east of Eneabba.

[2] This melaleuca occurs in the Nandanooka and Lesueur National Park areas[2] in the Avon Wheatbelt and Geraldton Sandplains biogeographic regions.
