Acacia parramattensis, commonly known as Parramatta wattle, is a tree of the family Fabaceae native to the Blue Mountains and surrounding regions of New South Wales. It generally grows in woodland or dry sclerophyll forest on alluvial or shale-based soils, generally with some clay content. It is a tall shrub or tree to about 15 m (50 ft) in height with finely divided bipinnate leaves and yellow flowers that appear over summer. A rapidly growing plant, it regenerates after bushfire by seed or suckering and can quickly colonise disturbed areas. Likewise it adapts readily to cultivation and is used in revegetation prpjects.
