Pedicularis is a genus of perennial green root parasite plants belonging to the broomrape family Orobanchaceae. Between 350-600 species are accepted by different authorities, mostly from the wetter northern temperate zones, as well as from South America. The highest diversity is in eastern Asia, with 352 species accepted in China alone by the Flora of China (not detailed here; see external links for details).

The common name lousewort, applied to several species, derives from an old belief that these plants, when ingested, were responsible for lice infestations in stock.
