Grevillea × gaudichaudii is a hybrid species of flowering plant in the family Proteaceae and is endemic to a restricted area of New South Wales.

It is a prostrate shrub with deeply lobed leaves and toothbrush-like groups of dark pink to burgundy-red flowers.

Its leaves are pinnately-lobed, the lobes oblong to egg-shaped and softly-hairy on the lower surface but not sharply pointed.

[2][3][4] Grevillea × gaudichaudii was first formally described in 1827 by Charles Gaudichaud-Beaupré in Voyage autour du monde, entrepris par ordre du roi from an unpublished description by Robert Brown of plants collected in the Jamieson Valley (near Katoomba).

[5][6] This grevillea grows in sandy soil and is restricted to parts of the higher Blue Mountains.
