Allocasuarina acutivalvis is a shrub or tree of the genus Allocasuarina native to the Wheatbelt, Goldfields-Esperance and Mid West regions of Western Australia..

The dioecious shrub or tree typically grows to a height of 2.5 to 8 metres (8 to 26 ft). It produces brown flowers and is found in tall, open woodland and rocky hillsides.

The species was first formally described as Casuarina acutivalvis by the botanist Ferdinand von Mueller in 1867 in the work Fragmenta Phytographiae Australiae. It was reclassified in 1982 into the Allocasuarina genus by Lawrence Alexander Sidney Johnson in the Journal of the Adelaide Botanic Gardens.
