"Iris missouriensis" is a species of iris found in western North America. Its distribution is varied; it grows at high elevations in mountains and alpine meadows and all the way down to sea level in coastal hills. Its common names include western blue flag and Rocky Mountain iris. The flower may be any shade of purple or blue-purple, often a light shade with darker veining.

This iris is considered a weed in some areas, particularly in California. It is bitter and distasteful to livestock and heavy growths of the plant are a nuisance in pasture land. Heavy grazing in an area promotes the growth of this hardy iris.
