Micromyrtus ninghanensis is a species of the flowering plant in the family Myrtaceae and is endemic to the south-west of Western Australia.

Micromyrtus ninghanensis is a low, spreading shrub that typically grows to 40 cm (16 in) high and has its leaves densely arranged near the ends of branchlets.

[3][1] Micromyrtus ninghanensis was first formally described in 2002 by Barbara Lynette Rye in the journal Nuytsia from specimens collected by Margaret Georgina Corrick in the Ninghan area, west-south-west of Paynes Find in 1984.

[3] This species is apparently restricted to the Ninghan area in the Yalgoo bioregion of south-western Western Australia where it grows on a greenstone-granite hill in low open woodland.

[3][1] Micromyrtus ninghanensis is listed as "Priority One" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[1] meaning that it is known from only one or a few locations which are potentially at risk.
