Marah macrocarpa is a species of plant in the genus Marah commonly referred to as chilicothe, wild cucumber, manroot or bigroot. It is a perennial herb with a large tuber native to Southern California and northern Baja California. It grows in a diverse number of habitats in coastal and inland regions.

All parts of the plant are toxic, as it contains cucurbitacins and ribosome-inactivating proteins.
