Micromyrtus navicularis is a species of flowering plant in the myrtle family, Myrtaceae and is endemic to a small area in the south of Western Australia.

[2] Micromyrtus navicularis was first formally described in 2006 by Barbara Lynette Rye in the journal Nuytsia from specimens collected near Mount Short, 14 km (8.7 mi) north-north-west of Ravensthorpe by Peter Gordon Wilson in 1968.

[3] The specific epithet (navicularis) means "boat-shaped", referring shape of the leaves.

[2] This species of micromyrtus grows in mallee, usually in gravelly sandy soils over granite or laterite, and is restricted to the range of hills near Ravensthorpe in the Esperance Plains and Mallee bioregions of southern Western Australia.

[2][4] Micromyrtus navicularis is classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife[4] meaning that it is poorly known and known from only a few locations but is not under imminent threat.
