Baalberith (Balberith) is a major Demon, one of the spirits possessing Sister Madeleine in the Aix-en-Provence Possessions. Baalberith was once a prince in the angelic order of Cherubim. According to Johann Weyer, Baalberith is the secretary and librarian of the archives in Hell and is a Demon of the second order, a master of the Infernal Alliance. He also is a grand pontiff and master of ceremonies. He countersigns or notarizes Pacts with the Devil. He tempts men to blasphemy and murder.
In the Aix-en-Provence case, Baalberith volunteered the names of all the Demons possessing Sister Madeleine, as well as the names of the saints who could counter them.
