Stephanomeria is a genus of North American plants also known as wirelettuce, ^[4] belonging to the tribe Cichorieae within the family Asteraceae. ^{[5] [6]}

Stephanomeria species are used as food plants by the larvae of some Lepidoptera species including Schinia scarletina , which feeds exclusively on the genus.
