Cassinia straminea is a species of flowering plant in the family Asteraceae and is endemic to eastern Australia.

It is an erect shrub with hairy young stems, linear leaves and corymbs of up to several hundred flower heads.

Flowering occurs from October to February and the achenes are about 0.7 mm (0.028 in) long with a pappus of 18 to 21 bristles.

[3][4] In 2004, Anthony Edward Orchard raised the variety to species status as Cassinia straminea in Australian Systematic Botany.

[5] Cassinia straminea grows in forest and on the edges of rainforest on the Northern Tablelands of New South Wales and in south-east Queensland.
