Primula pauciflora, the pretty shooting star, few-flowered shooting star, dark throat shooting star or prairie shooting star, is a species of flowering plant in the primula family Primulaceae. It is a widespread and very variable species, native to western North America, from Subarctic America to Mexico, often in xeric (extremely dry) and desert habitats. It is found in the Great Basin Deserts and Mojave Desert. Its synonyms include Dodecatheon pauciflorum and Dodecatheon pulchellum.

Primula pauciflora is a widespread and highly variable polyploid complex (2n = 44, 88 and 132). The species is generally hairless, with a flowering stem 10–40 cm (4–16 in) tall. The inflorescence is made up of between 2 and fifteen flowers. The flower generally has 9–14 mm (0.4–0.6 in) long petals, magenta to lavender in color.

Primula pauciflora has been divided into up to seven varieties each with their own often complex set of synonyms. Primula pauciflora var. pauciflora, synonym Dodecatheon pulchellum, is a herbaceous perennial with single, leafless flower stems, growing from very short erect root stocks with no bulblets. It grows to a height of 5–40 cm (2.0–15.7 in). Its leaves are basal, 2–15 cm long, blades oblong-lanceolate to oblanceolate, mostly entire to somewhat small-toothed, narrowed gradually to winged stalks nearly as long. Each plant has between 1 and 25 flowers clustered at the stem top. The calyx is usually purple-flecked, and the five lobes are 3 to 5 millimeters long. The corolla is 10 to 20 millimeters long, the 5 lobes swept backwards, purplish-lavender, seldom white, the short tube yellowish, usually with a purplish wavy line at the base. The filaments are joined into a yellowish tube 1.5–3 mm long, which is smooth or only slightly wrinkled. The 5 anthers are joined to a projecting point, usually yellowish to reddish-purple, 4–7 mm long. The stigma is slightly larger than the style. This plant flowers between April and August. The fruits are capsules, many-seeded, ovoid-cylindric, hairless to glandular-hairy, membranous to firm-walled, 5–15 mm long, opening from the tip into sharp teeth.
