Hieracium scouleri is a species of hawkweed known by the common name Scouler's woollyweed. It is native to western North America from Manitoba to California, where it grows in a variety of mountainous habitats. This plant produces a basal rosette of long, narrow leaves 10–20 centimetres (3.9–7.9 in) long, which are generally hairy to bristly. It bolts an erect stem 30–70 centimetres (12–28 in) tall which bears the inflorescence. The flower heads have large, curling bracts with glandular hairs or bristles, long, protruding disc florets and bright yellow ray florets. The achene is about 3 millimetres (0.12 in) long.

Flower heads have protruding disc florets and bright yellow ray florets (Mount Rainier National Park).

There are several varieties. One variety, var. albertinum, is often treated as a separate species, Hieracium albertinum.[1]
