Drusilla of Mauretania (Greek: Δρουσίλλη) may be the Drusilla mentioned by Tacitus as a granddaughter of Antonius and Cleopatra. If so, she would have been a princess of Mauretania, the youngest child of Queen Cleopatra Selene II and King Juba II and a sister to king Ptolemy of Mauretania. Her birthdate is uncertain but is thought to be about 8 BCE.[1]
