Olearia strigosa, commonly known as the bristly daisy bush, is a flowering plant in the daisy family found only in the south-west of Western Australia. It is an upright shrub up to about 0.5–1.5 metres tall, with stems and leaves covered in stiff bristles. The narrow leaves are only a few millimetres long. The flower heads are blue or purple and appear at the ends of branches; each head is about 11–20 mm across with 7–11 ray florets surrounding a cluster of disc florets. It flowers from January to May. The fruit is an achene with a pappus that has long and short bristles. The plant was first described in 1845 as Eurybia strigosa and renamed Olearia strigosa in 1867. The name strigosa means "bristly" or "hairy." It grows in the understorey of low woodlands in the southern Swan Coastal Plain and Jarrah Forest regions. It is listed as Priority Three – Poorly Known Taxa by Western Australia’s Department of Biodiversity, Conservation and Attractions, meaning it is known from only a few locations but is not currently considered under imminent threat.
