Rainiera is a monotypic genus of flowering plants in the daisy family, Asteraceae.

Rainiera stricta is of conservation concern, with a G2G3 ranking from NatureServe, and is considered to be globally imperiled.

[4] Rainiera stricta is an herbaceous perennial with both basal and cauline, alternate, petiolate leaves.

It is distinguished from Luina by the having fewer florets per head and a racemiform, rather than corymbiform, capitulescence.

[5] The genus was circumscribed by Edward Lee Greene in Pittonia vol.3 on page 291 in 1898.
