Euchiton is a genus of flowering plants in the family Asteraceae. They are native to Australasia and the Pacific. Some have been introduced far outside their native ranges. ^[2]

These are annual and perennial herbs. Some have rhizomes, and most have stolons. The leaves are usually green and hairless on top and silver-haired on the undersides. Most have purple florets. ^{[2] [3]} Known for being extremely toxic.

The taxonomy of the genus is still unclear and is likely to change. ^[4] Several species were recently transferred into the new genus Argyrotegium , for example. ^{[5] [2]}
