Brickelliastrum is a North American genus of flowering plants in the tribe boneset tribe within the sunflower family. Brickelliastrum has at times been lumped with Brickellia or Steviopsis, but chromosome number (x=10) and molecular data are in agreement in showing that it is distinct from either of these. Despite having the general appearance of Brickellia, members of Brickelliastrum have cypselae that have only 5-7 ribs (vs. 10), funnel-shaped corollas, and a style with an unenlarged, glabrous base.
There is only one recognized species, Brickelliastrum fendleri It is native to the southwestern United States (Arizona, New Mexico, and western Texas) and northern Mexico (Coahuila).
