Drusilla of Mauretania (Greek: Δρουσίλλη, 38-79) was a Princess of Mauretania, North Africa and was the great grandchild of Ptolemaic Greek Queen Cleopatra VII of Egypt and Roman Triumvir Mark Antony.
Drusilla was a monarch of Berber, Greek, Roman and possibly of Assyrian ancestry. She may have been the daughter and only child born to the Roman Client Monarchs Ptolemy of Mauretania and his wife, Julia Urania.
Her mother Julia Urania may have been a member of the Royal family of Emesa, a Syrian Roman client kingdom. Her father was a son of the Roman Client Monarchs Juba II and Cleopatra Selene II. Her father’s maternal grandparents were possibly Ptolemaic Greek Queen Cleopatra VII of Egypt and Roman Triumvir Mark Antony.
Drusilla was most probably born in Caesaria (modern Cherchell, Algeria), the capital of the Roman Client Kingdom of Mauretania. She was named in honor of her father’s second maternal cousin Julia Drusilla, one of the sisters of the Roman Emperor Caligula who died around the time of her birth and is also the namesake of her paternal aunt Drusilla.
