Pseudanthus ballingalliae is a species of flowering plant in the family Picrodendraceae and is endemic to Queensland.

Pseudanthus ballingalliae is an openly-branched shrub that typically grows to a height of up to 1.5 m (4 ft 11 in) and has glabrous, upwardly directed branchlets.

The flowers are arranged singly in upper leaf axils with small bracts at the base, but appear to be clustered on the ends of branches.

Flowering has been observed in September and October, and the fruit is a narrowly oval capsule 4.0–5.3 mm (0.16–0.21 in) long.

[2] Pseudanthus ballingalliae grows in shallow, sandy soil in forest or woodland on steep slopes and in gorges in the Carnarvon and Expedition National Parks.
