Eucalyptus chapmaniana, commonly known as the Bogong gum,[2] is a species of small to medium-sized tree endemic to montane and eastern Australia.

The adult leaves are lance-shaped to curved, the flower buds in groups of three and the fruit a conical or bell-shaped capsule.Eucalyptus chapmaniana is a tree that typically grows to a height of 30–35 m (98–115 ft) and forms a lignotuber.

[2][3][4][5][6] Eucalyptus chapmaniana was first formally described in 1947 by Alexander Kenneth Cameron from a specimen near Bogong and the description was published in The Victorian Naturalist.

[8] Bogong gum grows in wet forest and grassy or shrubby woodland, often on steep slopes, in cold mountains areas of Victoria and far southeastern New South Wales.

In Victoria it occurs along the highest parts of the Great Dividing Range between Jamieson and Benambra and is also found on Mount Buffalo and Pine Mountain.
