Silene marmorensis is a rare species of flowering plant in the family Caryophyllaceae known by the common names Marble Mountain catchfly,^[1] Marble Mountain campion, and Somes Bar campion. It is endemic to the southern Klamath Mountains of northern California, where it grows in mountain woodlands and forests. It is a perennial herb producing several stems and shoots from a woody, branching caudex and thick taproot. The hairy, glandular stems grow erect to a maximum height near 40 centimeters. The lance-shaped leaves are a few centimeters long and are borne in pairs, the lowermost drying early. The inflorescence is a terminal cyme of flowers at the top of the stem, and some flowers may occur in the leaf axils. Each flower has a hairy, veined calyx of fused sepals. The flowers bloom at night, the five pinkish or green-tinged petals opening at the tip of the calyx.

This species is threatened by logging operations and other degradation of its habitat.
