Gracia Mendes Nasi (1510 – 1569) was a Portuguese intellectual and one of the wealthiest Jewish women of Renaissance Europe. She married Francisco Mendes/Benveniste. She was the aunt and business partner of Joao Micas (alias, Hebrew name Joseph Nasi), who became a prominent figure in the politics of the Ottoman Empire. She also developed an escape network that saved hundreds of Conversos from the Inquisition. Her name Gracia is Spanish for the Hebrew Hannah, which means Grace; she was also known by her Christianized name Beatrice de Luna.
