"Hordeum" is a genus of about 30 species of annual and perennial grasses, native throughout the temperate Northern Hemisphere, temperate South America, and also South Africa.

One species, "H. vulgare" (barley), is of major commercial importance as a cereal grain, used as fodder crop and for malting in beer and whiskey production. Some species are nuisance weeds introduced world-wide by human activities others 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.
