Eucalyptus umbra, known as the broad-leaved white mahogany,[2] is a species of small to medium-sized tree that is endemic to northern New South Wales.

[2][3][4][5] Eucalyptus umbra was first formally described in 1901 by Richard Thomas Baker in Proceedings of the Linnean Society of New South Wales.

[3] The broad-leaved white mahogany occurs in the high rainfall coastal areas of New South Wales between Sydney and Grafton.

[2] It differs from the white mahogany (Eucalyptus latisinensis) of coastal Queensland in having broader juvenile leaves.

[3] Eucalyptus umbra is part of the white mahogany group as recognised by Ken Hill.
