The species was first formally described by the botanist George Bentham in 1842 as part of the William Jackson Hooker work Notes on Mimoseae, with a synopsis of species as published in the London Journal of Botany. It was reclassified as Racosperma sphacelatum by Leslie Pedley in 2003 then transferred back to the Acacia genus in 2006. The only other synonyms are Acacia sphacelata var. sphacelata, Acacia tamminensis and Acacia spacelata.[3]

There are three recognised subspecies:
