Francesco Aregazzi was a 14th-century Franciscan friar and Catholic bishop who served as the Ordinary of the Diocese of Bergamo. Born in Cremona in 1375, he joined the Order of Friars Minor Conventual, where his skill in oratory led to his appointment as custodian for the provinces of Bologna and Parma. At the age of 28, Pope Boniface IX appointed him to lead the Bergamo diocese, a role he held until his death in 1437.
