Euchloe hyantis, the pearly marble, pearly marblewing or California marble, is a butterfly in the Pieridae family. It is found on the West Coast of North America from southern Oregon south through California west of the Sierra Nevada crest to northern Baja California, Mexico. The habitat consists of rocky canyons, cliffs, moraines and gravelly flats.

The wingspan is 28–37 mm (1.1–1.5 in). The upperside of the forewing has a narrow cell bar very close to the edge of the wing. This cell bar is usually devoid of white scales. The underside is cream white, the hindwing with yellow-green to green marbling. Adults are on wing from April to early July in one generation per year. They feed on flower nectar, including that of the larval hosts and others such as tansymustard or pussypaws.

The larvae feed on the flowers and fruits of Brassicaceae species, especially Streptanthus species. Chrysalids hibernate.
