Chorizanthe is a genus of plants in the buckwheat family known generally as spineflowers. These are small, squat, herbaceous plants with spiny-looking inflorescences of flowers. The flowers may be in shades of red or yellow to white. The bracts are pointed and sometimes tipped with a hooked awn, and the inflorescence often dries into a rounded, spiny husk. Spineflowers are found in western North America and South America.

The word Chorizanthe comes from the Greek roots chorizo and anthos meaning "to divide," and "flower," thus meaning "divided flowers," but actually used in reference to the divided calyx.
