One species, Hordeum vulgare (barley), has become of major commercial importance as a cereal grain, used as fodder crop and for malting in the production of beer and whiskey. Some species are nuisance weeds introduced worldwide by human activities, others have become endangered due to habitat loss.

Hordeum species are used as food plants by the larvae of some Lepidoptera species, including the flame, rustic shoulder-knot and setaceous Hebrew character.

The name Hordeum comes from the Latin word for "to bristle" (horreō, horrēre), and is akin to the word "horror".
