Acacia acellerata is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia.

It is a rigid, mostly glabrous shrub with phyllodes that are more or less round on cross-section, heads of golden-yellow flowers, and linear, wavy pods.

Acacia acellerata is a rigid, spreading, domed shrub that typically grows to a height of 15–70 cm (5.9–27.6 in) and is more or less glabrous.

[2][3][4] Acacia acellerata was first formally described in 1927 by the Joseph Maiden and William Blakely in 1927 in the Journal of the Royal Society of Western Australia from specimens collected in the Stirling Range by Alexander Morrison.

[7] The species grows on undulating plains and along water courses[2] as a part of shrubland communities in loam or loamy sand soils.
