Acrotriche lancifolia is a species of flowering plant in the family Ericaceae and is endemic to the south-west of Western Australia.

It is an erect, widely branching shrub, with usually narrowly egg-shaped, sharply-pointed leaves, green or yellowish-green, tube-shaped flowers, and flattened spherical drupes.

[2][3] Acrotriche lancifolia was first formally described in 2007 by Michael Clyde Hislop in the journal Telopea from specimens collected in the Parker Range in 2003.

[5] This species grows on granite or laterite breakaways in shallow, rocky soil in open woodland and shrubland between Kondinin, Lake King and the Great Eastern Highway in the Avon Wheatbelt, Coolgardie and Mallee bioregions of south-western Western Australia.

[2][3] This species is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
