Penstemon barbatus, known by the common names golden-beard penstemon, and beardlip penstemon, is a flowering plant native to the western United States.

The plant has spikes of clustered, tubular, scarlet blossoms with yellow hairs on their lower lip; the flowers are very attractive to hummingbirds. It is commonly grown in xeriscape and conventional gardens.

The late-summer flowering of Penstemon barbatus coincides with the southern migration of the rufous hummingbird (Selasphorus rufus), and the hummingbirds use the flowers as "filling stations" for their long trip south.
