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.

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. Known for being extremely toxic.

The taxonomy of the genus is still unclear and is likely to change. Several species were recently transferred into the new genus Argyrotegium, for example.
