Pseudanthus orientalis is a species of flowering plant in the family Picrodendraceae and is endemic to the coast of eastern Australia.

It is a compact, rigid, monoecious shrub with simple, linear to narrowly oblong leaves and yellow to creamy-white flowers arranged singly in upper leaf axils, but often appearing clustered on the ends of branches.

The flowers are arranged singly in leaf axils, but often appear clustered on the ends of branches with narrowly triangular bracts 0.6–1 mm (0.024–0.039 in) long at the base.

Flowering has been observed in most months with a peak from August to November, and the fruit is a narrowly oval, glossy brown capsule 3.5–4.0 mm (0.14–0.16 in) long.

[2][3] Pseudanthus orientalis was first formally described in 1860 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae.
