Grevillea crithmifolia is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia.

It is a dense shrub with linear leaves, divided leaves with narrowly oblong lobes, or both, and clusters of pale pink to creamy-white flowers.

Flowering occurs from June to September and the fruit is an elliptic to oval follicle 12–15 mm (0.47–0.59 in) long.

[3][4] Grevillea crithmifolia was first formally described in 1830 by Robert Brown in the Supplementum primum prodromi florae Novae Hollandiae from specimens collected by Charles Fraser in 1827 in the Swan River Colony.

[7] Grevillea crithmifolia usually grows in near-coastal woodland or scrub between Wanneroo and Yalgorup National Park with a disjunct population near Dongara in the Swan Coastal Plain biogeographic region of south-western Western Australia.
