"Achnatherum" is a genus of plants which includes several species of needlegrass. Several needlegrass species have been switched between "Achnatherum" and genus "Stipa"; taxonomy between the two closely-related genera is still uncertain.

"Achnatherum hymenoides" was useful as a food source to Native Americans. "Achnatherum brachychaetum" is best known as a noxious weed.
