Allocasuarina huegeliana, commonly known as rock sheoak[3] is a species of flowering plant in the family Casuarinaceae and is endemic to Western Australia.

Allocasuarina huegeliana is a dioecious tree that typically grows to a height of 4–10 m (13–33 ft) and has dark, fissured bark.

[3][4][5] This species was first formally described in 1848 by Friedrich Anton Wilhelm Miquel who gave it the name Casuarina huegeliana in Lehmann's Plantae Preissianae, from specimens collected on Mount Brown near York in 1840 by Ludwig Preiss.

[9] Rock sheoak grows near granite in the south-west of Western Australia, where it in native in parts of its range, but naturalised in other places.

[3] Allocasuarina huegeliana is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
