Mimulus aurantiacus, the sticky monkey-flower or orange bush monkey-flower, is a flowering plant that grows in a subshrub form, native to southwestern North America from southwestern Oregon south through most of California. It is a member of the lopseed family, Phrymaceae, or, alternately, the Scrophulariaceae. It is treated by some botanists in a separate genus from other Mimulus as Diplacus aurantiacus.
