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

Micromyrtus rogeri is a shrub that typically grows to a height of 20–40 cm (7.9–15.7 in) with many erect stems arising from a lignotuber.

[2][3] Micromyrtus rogeri was first formally described in 2002 by Barbara Lynette Rye in the journal Nuytsia from specimens collected by Roger Hnatiuk about 30 km (19 mi) west-north-west of Arrino in 1980.

[2] This species of micromyrtus grows in sandy soils and gravel over laterite on breakaways near Arrino and Koojan in the Geraldton Sandplains and Jarrah Forest bioregions of south-western Western Australia.

[2][3] Micromyrtus rogeri is listed as "Priority One" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[3] meaning that it is known from only one or a few locations which are potentially at risk.
