Acacia bracteolata is a shrub belonging to the genus Acacia and the subgenus Phyllodineae endemic to Western Australia.

The spreading shrub typically grows to a height of 0.3 to 0.7 metres (1 to 2 ft).[1] The branchlets are hairy to villous and have 3 to 4 mm (0.12 to 0.16 in) long stipules. The asymmetric phyllodes have a narrowly elliptic to oblanceolate shape with a length of 15 to 25 mm (0.59 to 0.98 in) and a width of 5 to 10 mm (0.20 to 0.39 in).[2] It blooms in August and produces yellow flowers.[1] The rudimentary inflorescences mostly occur on two-headed racemes that have an axes with a length of less than 0.5 mm (0.020 in). The spherical flower-heads can have an obloid shape and have a diameter of 4.5 to 5.5 mm (0.18 to 0.22 in) containing 19 to 25 lemon yellow coloured flowers. The seed pods that form after flowering have a bow shape with a length of up to 6 cm (2.4 in) and a width of 6 to 7 mm (0.24 to 0.28 in). The dull black oblong-elliptic shaped seeds inside the pods are around 4 mm (0.16 in) in length.[2]

It is native to an area in the Goldfields-Esperance region of Western Australia where it is found east of Esperance growing in granitic sandy soils.[1] The shrub occurs from around Grass Patch in the north to Cape Arid National Park in the south and are often part of shrubland or low mallee communities.[2]
