Lithophragma parviflorum is a species of flowering plant in the saxifrage family known by the common name smallflower woodland star.

It is native to much of western North America from British Columbia to California to South Dakota and Nebraska, where it grows in several types of open habitat.

It is a rhizomatous perennial herb growing erect or leaning with a naked flowering stem.

The stem bears up to 14 flowers, each in a cuplike calyx of red or green sepals.

Its bulblets may produce toxins capable of poisoning livestock, although rodents eat them with no known adverse effects.
