Silene is a genus of flowering plants in the family Caryophyllaceae. Common names include "campion" (shared with the related genus Lychnis) and "catchfly".
Red Campion (S. dioica) and White Campion (S. latifolia) are common wildflowers throughout Europe and elsewhere. They readily hybridise to produce plants with paler pink flowers. The Moss campion is common in the high Arctic.
Silene species are used as food plants by the larvae of some Lepidoptera species - see list of Lepidoptera that feed on Silene.
