Micromyrtus sessilis is a species of flowering plant in the myrtle family, Myrtaceae and is endemic to eastern Australia.

Micromyrtus sessilis is a dense, spreading shrub growing to a height of 0.5–1.5 m (2–5 ft) and which has hairy young stems.

[2][3] Micromyrtus sessilis was first formally described in 1983 by John Green from a specimen collected near Miles and the description was published in Nuytsia.

[3][4] The specific epithet (sessilis) is a Latin word meaning "sitting"[5] referring to the flowers having a very short, or no peduncle.

[3] This species occurs between Miles in Queensland and Griffith in New South Wales, mainly above 600 m (2,000 ft), in a range of habitats from mallee to forest, often in rocky places.
