Bursaria occidentalis is a species of flowering plant in the family Pittosporaceae and is endemic to Western Australia.

It is a spiny tree or shrub with egg-shaped adult leaves, flowers with relatively small, hairy sepals and five spreading creamy-white petals, and inflated capsules.

Flowering occurs from August to December and the fruit is an inflated capsule 10–11 mm (0.39–0.43 in) long and wide containing winged, brown seeds.

[3][4] Bursaria occidentalis was first formally described in 1978 by Eleanor Marion Bennett in the journal Nuytsia from specimens she collected near Shark Bay in 1975.

[5][6] This bursaria grows in mallee woodland between Shark Bay, Dongara and Menzies in the Avon Wheatbelt, Coolgardie, Geraldton Sandplains, Murchison and Yalgoo biogeographic regions of Western Australia.
