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

It is a dense, erect to spreading shrub, usually with pinnatipartite to almost pinnatisect leaves, the end lobes linear, and clusters of yellowish-brown to fawn flowers with a scarlet to orange-red style.

Flowering occurs throughout the year with a peak between October and March, and the fruit a follicle 10–15 mm (0.39–0.59 in) long.

[3][4][5][6] Grevillea tetragonoloba 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.

[4][3] Grevillea tetragonoloba is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
