Harmonia hallii (formerly Madia hallii) is a species of flowering plant in the aster family known by the common names Hall’s harmonia and Hall’s madia. Harmonia hallii is endemic to California, where it is known only from a small section of the North Coast Ranges. It has been reported only from Yolo, Lake, Colusa, and Napa Counties. It grows in chaparral on serpentine soils, and its habitat is limited and being lost to activities such as mining.
