Erigeron clockeyi is found in the Great Basin and Sierra Nevada.

Perennials, 3–20(–30) cm; taprooted, caudices usually branched, retaining old leaf bases. Stems usually ascending to erect, moderately hirsute to hispidulous (hairs spreading-deflexed), minutely glandular at least distally. Leaves basal (persistent) and cauline (petioles prominently ciliate, hairs spreading, thick-based); basal blades 1–3-nerved, narrowly oblanceolate (often folding), 20–50(–80) × 1–5 mm, margins entire, faces strigose or hispidulous to hirsutulous, minutely glandular; cauline blades linear to linear-lanceolate, reduced distally to near heads. Heads 1(–2). Involucres 4–7 × 6–11 mm. Phyllaries in 2–3(–4) series (greenish), moderately hirsute, densely minutely glandular. Ray florets 20–40(–55); corollas blue, less commonly white to pink, 6–11 mm, laminae reflexing. Disc corollas 2.9–4.5 mm (throats tubular). Cypselae 1.8–2.5 mm, 2-nerved, faces sparsely strigose; pappi: outer of inconspicuous, fine setae, inner of (13–)20–27 bristles.

Erigeron clokeyi is a North American species of flowering plant in the family Asteraceae known by the common name Clokey's fleabane, or Clokey's daisy.

Erigeron clokeyiis native to the sage scrub of Nevada and far eastern California, and it can also be found in the talus of the eastern flank of Sierra Nevada. There are a few additional populations reported from Beaver County in Utah.

Erigeron clokeyiis a small perennial herb with leaves mostly around the base of the plant. The hairy, unbranching erect stems each hold an inflorescence of a single flower head which is about a centimeter (0.4 inches) wide. The head has a center of golden yellow disc florets and a fringe of sometimes as many as 55 very light to medium purple (occasionally white or pink) ray florets which are usually reflexed (bent away from the center).
