Diocirea violacea is a plant in the figwort family (Scrophulariaceae), and is endemic to a small area near Salmon Gums in Western Australia.

It is a low shrub with a restricted distribution but which often occurs in large numbers, forming a dense ground cover.

[2] Diocirea violacea was first formally described by taxonomist Bob Chinnock in Eremophila and allied genera: a monograph of the plant family Myoporaceae in 2007 from a specimen collected 26 kilometres (20 mi) south of Norseman.

[2] Diocirea violacea has a restricted distribution in a small area between Salmon Gums and Spargoville in the Coolgardie and Mallee biogeographic regions where it often grows as the dominant species on sandy, gravelly or clay soils.

[2][3][4] Diocirea violacea has been classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.
