Petrophile vana is a species of flowering plant in the family Proteaceae and is endemic to inland Western Australia.

It is a shrub with needle-shaped, sharply-pointed leaves, and spherical to oval heads of small numbers of hairy, white flowers.

The flowers are arranged in leaf axils in sessile, spherical to oval heads of up to four flowers, the heads 10 mm (0.39 in) long and 3–4 mm (0.12–0.16 in) wide, with about four overlapping, egg-shaped involucral bracts at the base.

[2][5] This petrophile is only known from a few locations in the Murchison and Yalgoo biogeographic regions where it grows in shallow, gritty clay soils over laterite, sometimes in heath with Thryptomene species.

[2][3] Petrophile vana is classified as "Priority One" by the Government of Western Australia Department of Parks and Wildlife,[3] meaning that it is known from only one or a few locations which are potentially at risk.
