Mirbelia viminalis is a species of flowering plant in the family Fabaceae and is endemic to northern Australia.

Flowering occurs in most months and the fruit is a pod 7–8 mm (0.28–0.31 in) long.

[2][3] This mirbelia was first formally described in 1837 by George Bentham in Commentationes de Leguminosarum Generibus from an unpublished description by Allan Cunningham who gave it the name Jacksonia viminalis.

[4] In 1930, Charles Gardner changed the name to Mirbelia viminalis in Enumeratio Plantarum Australiae Occidentalis.

[2][3] Mirbelia viminalis is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[2] and as of "least concern" in the Northern Territory and Queensland.
