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

The outer surface of the flower cup (the hypanthium) is hairy although it lacks the woolly, matted hairs of M. stramentosa.

Flowering occurs in October or November and is followed by fruit which are woody capsules 2.5–3 mm (0.098–0.12 in) long in loose clusters along the stem.

[2][3] Melaleuca similis was first formally described in 1999 by Lyndley Craven in Australian Systematic Botany from a specimen collected about 35 kilometres (20 mi) west of Scaddan.

[7] Melaleuca similis is listed as "Priority One" by the Government of Western Australia Department of Parks and Wildlife,[7] meaning that it is poorly known occurring in only a few locations and is potentially at risk.
