Chrysolina is a large genus of leaf beetles in the subfamily Chrysomelinae. Most species are distributed in Europe, Asia and Africa with a small number of species inhabiting North America (including introduced European ones) and introduced species in Australia.{{cite journal |last=Bieńkowski |first=Andrzej O.|date=2001 |title=A study on the genus Chrysolina MOTSCHULSKY, 1860, with a checklist of all the described subgenera, species, subspecies, and synonyms (Coleoptera: Chrysomelidae: Chrysomelinae) |journal=Genus - International Journal of Invertebrate Taxonomy |volume=12 |pages=105–235 |url=http://www.biol.uni.wroc.pl/cassidae/chrysolinachecklist.pdf |accessdate=2017-01-24 |archive-date=2016-03-04 |archive-url=https://web.archive.org/web/20160304192020/http://www.biol.uni.wroc.pl/cassidae/chrysolinachecklist.pdf |url-status=dead }}

The species Chrysolina cerealis and C. graminis are protected in the United Kingdom. All species of Chrysolina are phytophagous, feeding on specific food plants, and some of them have been used for biological control of weeds. To control Hypericum perforatum (St John's wort), C. hyperici was successfully naturalized in Australia in the 1930sW. T. Parsons, E. G. Cuthbertson. Noxious Weeds of Australia. 2nd ed.
