Cardamine depressa (common name - bitter cress) is a plant in the Brassicaceae family, found in the Antipodean Islands.

Cardamine depressa is a perennial herb, with erect hairless stems growing up to 20 cm high. The leaves may be hairless or hary and are brownish or green, leathery or thin. The basal leaves are simple and may be crenate or entire. The petals are white and 2–3 by 0.6–1 mm. There are six stamens. The brown seeds are circular to oblong, and 0.8–1 mm in length.

It can be found flowering from October to March, and fruiting from November to March.

According to Hooker, it is found "in gravelly moist places near the sea amongst grass".
