Boechera falcatoria (formerly Arabis falcatoria) is a rare species of flowering plant in the mustard family known by the common name Grouse Creek rockcress. It is endemic to Utah in the United States, where it is known only from Box Elder County. It has been reported from neighboring Nevada, but these reports are likely based on misidentifications. This plant grows on open rocky outcrops in sand and gravel. This species is known from a few collections and little else is known about its abundance.
