Acacia aculeiformis is a prostrate, scrambling, mat-forming shrub that has many stems and that typically grows up to wide.

Between 27 and 39 light to medium golden-yellow or yellowish-red flowers are arranged in 1 or 2 spherical heads long on a peduncle long. Flowering has been observed from August to January.[1] [2] [3]
Acacia aculeiformis was first formally described in 1999 by Bruce Maslin in the journal Nuytsia from specimens he collected north of Three Springs in 1983.[4] The specific epithet (aculeiformis) means "prickle-shaped" and refers to the stipules.[5]
This species of wattle occurs in scattered locations from Mogumber and Three Springs in gravelly soils on rocky rises, breakaways and hills in the Avon Wheatbelt, Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia.
