Angelo Giori (Capodacqua di Pieve Torina, 11 May 1586 – Rome, 8 August 1662) was an Italian cardinal.
The son of Giovanni Francesco Giori and Polidora Polini, he came from humble origins. He began his studies at the Grammatica at Camerino and completed them at the Archiginnasio in Rome, where he graduated in civil and criminal canon law. Allying himself with his uncle Cesareo Giori, Angelo entered the service of cardinal Maffeo Barberini, later to become pope Urban VIII (1623–1644), becoming his secretary. Urban made him a cardinal in the consistory of 13 July 1643 and on 31 August that year he received the purple and the titulus of Santi Quirico e Giulietta. He took part in the 1644 and 1655 conclaves and built the Villa La Maddalena at Muccia. His portrait was painted by Andrea Sacchi (1599–1661). On his death in 1662 he was buried at Camerino in the church of Santa Maria in via.
