Allocasuarina crassa, commonly known as Cape Pillar sheoak, is a species of flowering plant in the family Casuarinaceae and is endemic to a small area in far south-eastern Tasmania. It is a low shrub to small tree that is monoecious or dioecious, with spreading to erect branchlets up to 170 mm (6.7 in) long, the leaves reduced to scales in whorls of seven to ten, the fruiting cones 15–34 mm (0.6–1 in) long containing winged seeds (samaras) 5–8 mm (0.2–0.3 in) long.
Endemic to Tasmania, A. crassa is restricted to the Cape Pillar area of the Tasman Peninsula and Tasman Island, both of which are in the Tasman National Park where there are about 100,000 mature individuals. It has a linear extent of distribution of 10 km (6.2 mi) with an area of about 20 km2 (7.7 sq mi). It grows on dolerite soils in both wet eucalypt forest and in coastal heath and shrubland. On the Cape Pillar plateau it may occur in pure, even-age stands after a long fire-free period.
