Acacia anserina, also known as hairy sandstone wattle, is a shrub of the genus Acacia and the subgenus Plurinerves. It is native to a small area in the Kimberley region of Western Australia.

Description
The shrub typically grows to a height of around  and has an erect, openly branched habit. It has ribbed branchlets that are densely hairy and has persistent stipules that are  in length. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen dimidiate phyllodes have a widely elliptic or occasionally widely obovate shape with a rounded upper margin and a more or less straight lower margin. The hairy phyllodes are  in length and  wide and have many longitudinal indistinct nerves. When it blooms it produces simple inflorescences with spherical flower-heads containing 17 to 25 light golden coloured flowers. Following flowering flat and narrowly oblong red-brown seed pods form that are  in length.

Taxonomy
The species was first formally described by the botanists Bruce Maslin, Matthew David Barrett and Russell Lindsay Barrett in 2013 as part of the work A baker's dozen of new wattles highlights significant Acacia (Fabaceae: Mimosoideae) diversity and endemism in the north-west Kimberley region of Western Australia as published in the journal Nuytsia.

Distribution
It is confined to a small area in the Princess May Range on gentle slopes under sandstone ridges among a fire-protected pocket of dense vegetation in the west Kimberley.
