Grevillea stenogyne is a species of flowering plant in the family Proteaceae and is only known from the type collection, made in the southwest of Western Australia.

It is a shrub with divided leaves, the end lobes triangular and sharply-pointed, and clusters of white flowers.

The edges of the leaves are rolled under, but the lower surface is mostly exposed and woolly-hairy.

[4][5] In 2000, Robert Owen Makinson raised the variety to species status as Grevillea stenogyne in the Flora of Australia.

[2] Grevillea stenogyne is listed as "Priority One" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[3] meaning that it is known from only one or a few locations that are potentially at risk.
