Micromyrtus acuta is a small flowering shrub in the myrtle family that grows only in the southwest of Western Australia. It reaches about 0.8–2 meters tall and has upward-pointing, thick, blunt oblong leaves about 1.5–1.8 mm long and 0.6–0.8 mm wide, usually clustered at the ends of branches.

The tiny white flowers are 4–5 mm wide and occur in the upper leaf axils, with short stalks and small bracteoles at the base. Each flower has ten stamens.

This species was first described in 2006 by Barbara Rye, from specimens collected near Paynes Find in 1977. The name acuta means “sharply pointed,” referring to the pointed tips of the buds and sepals.

Micromyrtus acuta grows in open shrubland from near Lake Monger to near Paynes Find, in the Avon Wheatbelt and Yalgo bioregions of south-western Western Australia. It is classified as Priority Three — Poorly Known Taxa (DEC), meaning it is known from only a few locations and is not currently believed to be under imminent threat.
