Acacia amblyophylla is a species of flowering plant in the family Fabaceae and is endemic to an area near Shark Bay in the north-west of Western Australia.

It is a bushy shrub or tree with a dense crown, many suckers, lance-shaped phyllodes with the narrower end towards the base, golden-coloured flowers arranged in spherical heads each of 24 to 26, and broadly linear to narrowly oblong pods up to 200 mm (7.9 in) long.

The phyllodes are narrowed at both ends, with 1 or 2 obscure glands 10–35 mm (0.39–1.38 in) above the base.

[2][3] Acacia amblyophylla was first formally described in 1882 by Ferdinand von Mueller in the Southern Science Record from specimens he collected near Shark Bay.
