Gompholobium marginatum is a prostrate or low, spreading shrub that typically grows to a height of 5–40 cm (2.0–15.7 in) with spiny stems. Its leaves are palmate, 10–25 mm (0.39–0.98 in) long and sessile. The flowers are uniformly yellow, borne on glabrous pedicels 10–12.7 mm (0.39–0.50 in) long with bracteoles attached. The sepals are glabrous, 5.5–8 mm (0.22–0.31 in) long, the standard petal 8–10 mm (0.31–0.39 in) long, the wings 6.5–8 mm (0.26–0.31 in) long and the keel 6–7 mm (0.24–0.28 in) long. Flowering occurs from August to November and the fruit is a pod about 10 mm (0.39 in) long.

Gompholobium marginatum grows in gravelly or granitic soils in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Mallee, Swan Coastal Plain and Warren biogeographic regions of south-western Western Australia.
