Rorippa is a flowering plant genus in the mustard family, Brassicaceae, native to Europe through central Asia, Africa, and North America. Rorippa species are annual to perennial herbs, usually with yellow flowers and a peppery flavour. They are known commonly as yellowcresses.

Rorippa formerly included several species of watercress, now placed in the genus Nasturtium. In particular, R. nasturtium-aquaticum (now N. officinale) and R. microphylla (now N. microphyllum) are often referred to as species of Rorippa.
