Ixeris is a genus of Asian flowering plants in the family Asteraceae.[2]

Concepts of which species should be included in the genus have changed in recent years because of the use of molecular investigations.[3] Numerous species formerly regarded as members of Ixeris have been moved to other genera; (Agoseris, Crepidiastrum, Ixeridium, Lactuca, Paraixeris, Paraprenanthes, Sonchella or Youngia).[1] Species remaining in Ixeris or of uncertain affiliations are listed below.
