Grevillea triloba is species of flowering plant in the family Proteaceae and is endemic to near Geraldton in Western Australia.

Flowering mainly occurs from July to October, and the fruit is an oblong to elliptic follicle 8–10 mm (0.31–0.39 in) long with a wrinkled surface.

[2][3][4] Grevillea triloba was first formally described by the botanist Carl Meissner in 1855 in William Jackson Hooker's Journal of Botany and Kew Garden Miscellany from specimens collected by James Drummond.

[2][3] Grevillea triloba is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[3] meaning that it is poorly known and known from only a few locations but is not under imminent threat.

[8] Commonly cultivated, G. triloba is a vigorous plant that is suited to most soils and aspects.
