Grevillea trifida is species of flowering plant in the family Proteaceae and is endemic to the southwest of Western Australia.

It is a spiny, erect to low spreading shrub, usually with divided, variably-shaped leaves, and clusters of white to cream-coloured flowers.

The leaf lobes are sharply pointed, and the edges of the leaves turned down to rolled under without concealing the lower surface.

[2][3][4] This species was first formally described in 1810 by Robert Brown who gave it the name Anadenia trifida in Transactions of the Linnean Society of London.

[9] Grevillea trifida grows in sandy or gravelly soils in jarrah forest, shrubland and in swampy places.
