Eucalyptus acmenoides, commonly known as white mahogany or barayly,[3] is a species of tree that is endemic to eastern Australia.

It is a large tree with grey to reddish brown, stringy bark, lance-shaped leaves, oval to spindle-shaped buds and more or less hemispherical fruits.

[4][5][6] Eucalyptus acmenoides was first formally described in 1843 by Johannes Conrad Schauer from a specimen collected by Allan Cunningham in a forest in New South Wales in January 1817.

The description was published in Wilhelm Gerhard Walpers' book Repertorium Botanices Systematicae (Volume 2).

[11] White mahogany grows in wet forest and woodland, in deeper soils with reliable moisture and is found between areas near the Atherton Tableland in Queensland and south to Port Jackson.

The timber has various uses, including heavy engineering, poles, railway sleepers, bridge and wharf construction, framing, decking stumps, fence posts, joists, flooring, plates and weatherboarding.
