Giovanni Guidiccioni (1480–1541) was an Italian poet.
He was born at Lucca, and died at Macerata.
He occupied a high position, being bishop of Fossombrone and president of Romagna. The latter office nearly cost him his life; a murderer attempted to kill him, and had already touched his breast with his dagger when, conquered by the resolute calmness of the prelate, he threw away the weapon and fell at his feet, asking forgiveness.
The Rime and Letters of Guidiccioni are models of elegant and natural Italian style.
