Francesco Alidosi (1455 – 24 May 1511) was an Italian cardinal, diplomat and condottiero, remembered as a friend and favourite of Pope Julius II, used by Michelangelo to smooth his relations with his difficult patron. He accompanied Giuliano della Rovere to France in 1494, and continued in favour when Della Rovere was elected pope, becoming Pope Julius II. Alidosi was elected as bishop of Mileto in 1504, and then transferred to the see of Pavia on 26 March 1505. He occupied the seat until his murder in 1511.
