Gompholobium polyzygum is a species of flowering plant in the family Fabaceae and is endemic to north-western Australia.

It is an erect or prostrate shrub with pinnate leaves each with sixteen to twenty-one pairs of leaflets, and yellow-orange and greenish, pea-like flowers.

[2][3] Gompholobium polyzygum was first formally described in 1862 by Ferdinand von Mueller in Fragmenta phytographiae Australiae.

[4][5] The specific epithet (polyzygum) means "many-yolked", referring to the many leaflets of each leaf.

[6] This gompholobium grows open shrubland and grassland in arid inland areas of the Northern Territory and Western Australia.
