Eucalyptus griffithsii, commonly known as Griffith's grey gum,[2] is a species of mallee or tree that is endemic to Western Australia.

It has smooth grey to whitish bark, sometimes with rough, loose fibrous bark near the base of the trunk, lance-shaped adult leaves, flower buds in groups of three, white flowers and conical to cup-shaped fruit.Eucalyptus griffithsii is a mallee or tree that typically grows to a height of 3–10 m (9.8–32.8 ft) and forms a lignotuber.

[2][3][4] Eucalyptus griffithsii was first formally described in 1911 by Joseph Maiden in the Journal of the Natural History and Science Society of Western Australia.

The specific epithet (griffithsii) honours John Moore Griffiths for his interest in the work of Maiden over "nearly thirty years".
