Gentile Brancaleoni (1416 – Urbino, 27 July 1457), was the daughter of Bartolomeo Brancaleoni, Lord of Massa Trabaria and Count of Mercatello sul Metauro, and Giovanna Alidosi,daughter of Bertrando Alidosi. The name "Gentile" is, now as then, both masculine and feminine; in fact, she was named after her paternal grandfather.
