Hymenoxys hoopesii (formerly Dugaldia hoopesii) is a species of flowering plant in the daisy family known by the common names owl's claws and orange sneezeweed. It is native to the western United States, where it grows in habitats of moderate elevation, such as mountain meadows. It is an erect perennial herb approaching a meter in maximum height, with smooth-edged leaves oval on the lower stem and lance-shaped toward the top. The flower cluster bears several flower heads on erect peduncles, each lined with a base of hairy, pointed phyllaries. The flower head has a center of disc florets fringed with many orange or yellow ray florets up to 3.5 centimeters long. The fruit is an achene with a pappus of scales.
