Chaenactis douglasii is a North American species of flowering plant in the daisy family known by the common name Douglas' dustymaiden.

Chaenactis douglasii is a variable herb, generally a perennial. It grows erect to 10–60 centimetres (4–24 inches), with one to many stems coated in cobwebby hairs. The woolly or hairy leaves may be up to 15 cm (6 in) long and are divided intricately into many lobes with curled or twisted tips. Stem leaves become smaller and stalkless upwards.

The inflorescence produces one or more flower heads, each up to about 2 cm (3⁄4 in) long. The flower head is lined with flat, glandular, blunt-pointed phyllaries and contains several white or pinkish tubular disc flowers with protruding anthers.

The fruit is an achene about 1 cm (3⁄8 in) long including its pappus of scales.
