Eucalyptus cornuta, commonly known as yate,[3] is a tree species, sometimes a mallee and is endemic to the southwest of Western Australia.

Labillardière collected the type specimen from granite outcrops on Observatory Island west of Esperance on 13 December 1792 during the Bruni d'Entrecasteaux expedition.

[7] In more arid regions near Esperance, it is often at granite outcrops, on deeper and wetter soil at cavities on the rock or the apron beneath the rockface.

Vigorous early growth and the potential in its lignotuber allow it to generate new stems after fire or as new opportunities emerge in the canopy or surroundings.

[8] Ferdinand von Mueller sent seed of the species to Lucknow, where the sapling grew to a height of eight to ten feet within a year and, unlike eucalypts tested, tolerated tropical rain; his 1879 report also noted the successful introduction to Melbourne.

[17] This eucalypt produces one of the hardest and strongest timbers in the world and was formerly used for wheel spokes and the shafts of horse-drawn vehicles but most trees of commercial value were logged a long time ago.
