Claudia Auditore da Firenze (1461 – unknown) was a Florentine noblewoman during the Renaissance, and a member of the Italian Brotherhood of Assassins. She was the sister of Ezio Auditore da Firenze, who became the Mentor of the Italian Brotherhood. In 1476, Claudia became the financial accountant of the town of Monteriggioni, which was under the leadership of her uncle Mario Auditore. The town flourished with Claudia's organization and the money made from Monteriggioni's shops and organizations, which had been opened once more.
