Grevillea wiradjuri is species of flowering plant in the family Proteaceae and is endemic to inland New South Wales.

Grevillea wiradjuri is an open, erect or dwarf shrub that typically grows to a height of 0.2–1.8 m (7.9 in – 5 ft 10.9 in), and sometimes forms a rhizome.

The flowers are arranged in sessile clusters of 8 to 20 on the ends of branches and surrounded by the foliage, the pistil 7–9 mm (0.28–0.35 in) long.

The flowers are white, sometimes becoming slightly pink or red as they age, and the style is strongly curved near its tip.

[2][3] Grevillea wiradjuri was first formally described in 2000 by Robert Makinson in the Flora of Australia from specimens collected by Michael Crisp near Temora in 1988.
