Collinsonia is a genus of flowering plants in the family Lamiaceae. It is native to East Asia and eastern North America.[1][2][3][4] It was named for the English botanist Peter Collinson (1694–1768) by Carl Linnaeus in Species Plantarum in 1753.[5] It is in the tribe Elsholtzieae, a small tribe of only 5 genera.[6] In order of their number of species, they are Elsholtzia, Mosla, Collinsonia, Perilla, and Perillula.

The circumscription of species in Collinsonia has been a source of confusion, and many names have been published.[7] Some authors have recognized as many as 10 species. In 2006, the genus was revised with only four species recognized.[8] The following list of species follows the World Checklist from Kew Gardens in London.
