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

It is an erect, prickly shrub with divided leaves with 3 lobes, and clusters of red and cream-coloured or reddish-orange and yellow flowers.

[2][3][4] Grevillea tripartita was first formally described in 1856 by Carl Meissner in de Candolle's Prodromus Systematis Naturalis Regni Vegetabilis from specimens collected by James Drummond in the Swan River Colony.

[7] In 2000, Robert Makinson described two subspecies of G. tripartita in Flora of Australia, and the names are accepted by the Australian Plant Census: Subspecies macrostylis grows in mallee heath and coastal heath and is common on the south coast of Western Australia between East Mount Barren and Point Culver in the Esperance Plains bioregion.

[10][11] Both subspecies of G. tripartita are listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
