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

It is a shrub with sticky, hairy foliage, linear leaves, and heads of creamy-white flowers arranged in a dense panicle.

The flower heads are oblong to bell-shaped, 2.5–3 mm (0.098–0.118 in) long and 1.0–3.0 mm (0.039–0.118 in) wide, each with five or six creamy-white florets surrounded by four or five overlapping rows of involucral bracts.

[2] Cassinia quinquefaria was first formally described in 1818 by Robert Brown in the Transactions of the Linnean Society of London.

[3][4] This cassinia grows in woodland and forest and is widespread in eastern New South Wales, the Australian Capital Territory and south-eastern Queensland.
