Elymus svensonii, commonly called Svenson's wildrye, is a species of flowering plant in the grass family (Poaceae). It is native to United States, where it is endemic to the Interior Low Plateau of Kentucky and Tennessee. Its natural habitat is on dry, rocky, limestone river bluffs. Elymus svensonii is a perennial grass. It is similar to Elymus hystrix, with which it sometimes hybridizes. It can be distinguished from Elymus hystrix by its curving lemma awns, generally larger glumes, and nodding spikes.
