Petrophile macrostachya is a perennial species of shrub in the plant genus Petrophile. It is endemic to south-west Western Australia growing on sandy and gravel soils from Perth through to north of Kalbarri.

It grows as a spreading shrub to about one and a half metres in height. The lobed leaves are mucronulate (pointed). The apical (terminal) inflorescences of cream to white flowers appear from winter to late spring (July to November).

This species was first published by Robert Brown in his 1830 Supplementum primum Prodromi florae Novae Hollandiae.

It occurs in south-west Western Australia from just south of Perth to north of Kalbarri, not extending far inland. The soils types are premoninantly sandy and sometimes gravelly.
