Pultenaea spinulosa is a species of flowering plant in the family Fabaceae and is endemic to the south of Western Australia. It is a shrub with flat, hairy leaves, and uniformly yellow flowers.

Description
Pultenaea spinulosa is a shrub that typically grows to a height of 15–40 cm and has hairy stems. The leaves are flat, 7–8 mm long and 2.0–2.5 mm wide with stipules at the base. The flowers are uniformly yellow, each flower on a hairy pedicel 2.0–2.5 mm long with hairy bracteoles 4.0–4.6 mm long attached to the pedicel.

In 1864, George Bentham changed the name to Pultenaea spinulosa in Flora Australiensis. The specific epithet (spinulosa) means "spiny", referring to the tips of the leaves.
