Acacia enterocarpa, commonly known as jumping jack wattle, is a shrub species that is endemic to eastern Australia.

The phyllodes are straight to shallowly recurved and have a length of 1.5 to 4.5 cm (0.59 to 1.77 in) and a width of 1 to 1.3 mm (0.039 to 0.051 in) and have 10 to 12 distant raised nerves.

The dull dark brown to black coloured seeds in the pods have an oblong to elliptic shape and are around 3 mm (0.12 in) in length.

[3] The species was first formally described by the botanist R.V.Smith in 1957 as part of the work A remarkable new Acacia for Victoria (The "Jumping-Jack" Wattle) as published in The Victorian Naturalist.

It was reclassified as Racosperma enterocarpum in 2003 by Leslie Pedley then transferred back to genus Acacia in 2005.
