Adenanthos labillardierei is a species of erect shrub endemic to the slopes of the Barren Ranges in the Fitzgerald River National Park in southwest Western Australia.

Like many Adenanthos species, its leaves are deeply divided into long, soft, slender laciniae, in this case usually five, but occasionally up to nine.

[1][2] This species is very similar in appearance to its close relative A. filifolius, but the latter has cream and black or dark navy blue flowers, and leaves with many more laciniae than A. labillardierei.

Nelson based his concept of the species on a specimen collected by him in 1973 from a track on the eastern side of Whoogarup Range in the Fitzgerald River National Park.

[1] Adenanthos labillardierei is unknown in cultivation, and is unlikely to have much potential as an ornamental, because the very similar A. filifolius is a more attractive plant.
