Acacia brownii, commonly known as heath wattle, is an erect or spreading shrub which is endemic to eastern Australia.

The globular yellow flowerheads with a diameter of 5 to 10 mm (0.20 to 0.39 in) and containing 12 to 30 flowers appear singly in the leaf axils from August to November.

Following flowering curved flat, seed pods form that are 1.5 to 8 cm (0.59 to 3.15 in) long and 3 to 5 mm (0.12 to 0.20 in) wide.

The current name was published by botanist Ernst Gottlieb von Steudel in 1821 as part of the work Phanerogams.

[4] The species occurs on sandy or clay loam in dry sclerophyll forest, woodland or heath in southern and eastern Victoria, New South Wales and Queensland.
