Castilleja is a genus of about 200 species of annual and perennial herbaceous plants native to the west of the Americas from Alaska south to the Andes, as well as northeast Asia. Formerly classified in the family Scrophulariaceae, they have recently been relegated to the family Orobanchaceae as a consequence of molecular systematics research (see Angiosperm Phylogeny Group). They are commonly known as Indian paintbrush or Prairie-fire. They are semi-parasitic on the roots of grasses.

Castilleja species are used as food plants by the larvae of some Lepidoptera species including Schinia cupes (which has been recorded on C. exserta) and Schinia pulchripennis (which feeds exclusively on C. exserta). Also checkerspot butterflies such as Euphydryas.

One of the species of this genus, Indian paintbrush (Castilleja linariaefolia ) was adopted on January 31, 1917 as the state flower of Wyoming.

Possibly Castilleja chromosa, "Desert Paintbrush", at the Sandia Mountains.

Unidentified Castilleja species found near Greenhorn Mountain, in the Wet Mountains.

Castilleja exserta, Owl's Clover from near Harquahala Mountains, Arizona, USA. This species was formally classified as Orthocarpus.
