Boechera constancei is a species of flowering plant in the mustard family known by the common name Constance's rockcress.

This is a perennial herb growing from a branching, woody caudex. It produces one or more erect, hairless stems to maximum heights between 15 and 30 centimeters. The caudex is surrounded by a dense basal rosette of stiff, blue-green, lance-shaped leaves up to 3 centimeters long. There may be a few smaller leaves along the stem. The inflorescence produces 5 to 10 white mustardlike flowers with protruding stamens. The fruit is a hanging green silique 4 or 5 centimeters long which contains round, winged seeds.
