Austrostipa crinita is a species of grass that grows in coastal parts of midwest Western Australia.

[1] It was first collected from Shark Bay in Western Australia by Charles Gaudichaud-Beaupré, botanist to the expedition of Louis de Freycinet.

That name remained current until 1996, when the Australian species of Stipa were recognised as meriting their own genus.

Thus Austrostipa was erected, and this and other species were transferred into it.

[2] It occurs on sand and limestone in coastal areas of midwest Western Australia,[1] including offshore islands such as those of the Houtman Abrolhos.
