Hordeum brachyantherum, known by the common name Meadow barley, is a species of barley. It is native to western North America from Alaska to northern Mexico, coastal areas of eastern-most Russia (Kamchatka), and a small area of coastal Newfoundland.
This is a tufting perennial bunchgrass approaching a meter in maximum height. It produces compact, narrow inflorescences 8 to 10 centimeters long and purplish in color. Like other barleys the spikelets come in triplets. It has two small, often sterile lateral spikelets on pedicels and a larger, fertile central spikelet lacking a pedicel.
