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

The dense domed shrub typically grows to a height of 1.0 to 1.6 metres (3 to 5 ft) and 3.0 metres (10 ft) wide.[1] The smooth dull green phyllodes have an elliptic to obovate shape. The phyllodes are around 10 to 15 mm (0.39 to 0.59 in) in length and have a width of 5 to 9 mm (0.20 to 0.35 in) with obscure midrib and lateral nerves.[2] It blooms from August to September producing yellow flowers.[1] The inflorescences are found in groups of seven to ten. The spherical flower-heads contain 15 to 21 bright golden yellow flowers. The narrowly oblong brown seed pods that form after flowering have a length of around 6 cm (2.4 in) and a width of 11 mm (0.43 in). The oblong-elliptic shaped seeds have a length of up to 4 mm (0.16 in).[2]

It is a member of the Acacia prainii and resembles Acacia camptoclada and some forms of Acacia merrallii.[2]

It is native to a small area in the Goldfields-Esperance region of Western Australia in a small area in the Dundas where it is found on low rocky hills growing in rocky sandy-loam-clay soils.[1] Only two populations of the shrub are known both of which are located about 25 km (16 mi) to the north of Norseman in mallee or shrubland communities.[2]
