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

It is an intricately-branched shrub with narrowly oblong to lance-shaped, sometimes linear phyllodes, spherical heads of 20 to 30 golden-yellow flowers, and leathery pods up to 65 mm (2.6 in) long.

[2][3][4] Acacia andrewsii was first formally described in 1904 by the botanist William Vincent Fitzgerald in the Journal of the West Australian Natural History Society from specimens collected in 1903.

[5][6] The specific epithet (andrewsii) honours Cecil Rollo Payton Andrews who bought the species to the attention of Fitzgerald.

[6] This species of Acacia often grows in low lateritic or limestone hills and granite outcrops in a variety of soil types in the Avon Wheatbelt, Coolgardie, Geraldton Sandplains, Mallee, Murchison and Yalgoo bioregions of south-western Western Australia.
