Allocasuarina campestris is a species of flowering plant in the family Casuarinaceae and is endemic to the south-west of Western Australia.

Female cones are red to brown, covered with short, fine, white hairs when young, and are sessile or on a peduncle up to 5 mm (0.20 in) long.

[2] This species was first formally described in 1904 by Ludwig Diels who gave it the name Casuarina campestris in Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie, from specimens collected near Watheroo.

[5] The specific epithet (campestris) means "pertaining to plains or flat areas, as opposed to hills and mountains".

[6] Allocasuarina campestris is widespread in the south-west of Western Australia, from north of the Murchison River almost to the south coast near Ravensthorpe and to east of Esperance, where it grows on sandplains.
