Diocirea acutifolia is a plant in the figwort family, Scrophulariaceae and is endemic to a small area near Norseman in Western Australia.

This species is distinguished from the three others in the genus by its leaves which are longer than 6 millimetres (0.2 in) and the prominent resin glands on its stems.

[2] Diocirea acutifolia was first formally described by taxonomist Bob Chinnock in Eremophila and allied genera: a monograph of the plant family Myoporaceae in 2007[1][2] from a specimen collected near Kambalda, about 45 kilometres (30 mi) north of the Lake Cowan Causeway.

[2] Diocirea acutifolia occurs in a small area north of Norseman in the Coolgardie biogeographic region where it grows in woodland on gravelly loam.

[2][3][4] Diocirea acutifolia has been classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife[3] meaning that it is poorly known and known from only a few locations but is not under imminent threat.
