Crepis occidentalis is a North American species of flowering plant in the daisy family known by the common names western hawksbeard,[2]:119 or largeflower hawksbeard. It is native to western Canada (British Columbia, Alberta, Saskatchewan) and the western United States (from the Pacific to the western Great Plains).

Crepis occidentalis grows in many types of habitat. It is a perennial herb growing a grayish woolly branching stem to about 40 centimeters (16 inches) in height from a deep taproot. The woolly, toothed leaves are up to 30 centimeters (12 inches) long at the base of the plant. The inflorescence produces several clusters of flower heads with hairy, often glandular phyllaries and many yellow ray florets but no disc florets. The fruit is a ribbed achene with a frilly pappus at the tip.[3]
