Acacia venulosa, commonly known as veiny wattle[1] or veined wattle,[2] is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to an area of eastern Australia.

[4] The ascending, thinly leathery and glabrous to slightly hairy phyllodes have a narrowly elliptic shape and are straight to incurved with a length of 5 to 9 cm (2.0 to 3.5 in) and a width of 4 to 15 mm (0.16 to 0.59 in).

[4] The species was first formally described by the botanist George Bentham in 1842 as a part of the work Notes on Mimoseae, with a synopsis of species as published in the London Journal of Botany.

It was reclassified by Leslie Pedley in 1987 as Racosperma venulosum then transferred back to genus Acacia in 2006.

In New South Wales it is found to the north of Corindi Beach and the Northern Tablelands from around Armidale and the north western slopes around Howell where it is found growing in stony and sandy soils over and around areas of granite and sandstone as a part of open Eucalyptus forests and woodlands and heathsland communities.
