Charles Reynolds () (c. 1496July 1535) was an Irish Catholic cleric, canonist, and diocesan administrator. Born in County Leitrim, son of Marcus MacRaghnaill, Reynolds entered a religious order and was appointed to influential posts as archdeacon and chaplain to the Earl of Kildare. His name in native Irish is , but he anglicized his name to Charles Reynolds in order secure ecclesiastical benefices under English laws. He was educated at the University of Oxford and fluent in English, Irish, and Latin. Reynolds opposed Henry VIII of England's separation from the Catholic Church, declining to acknowledge him as Supreme Head of the Church of England and refusing to acknowledge the annulment of his marriage to Catherine of Aragon. During the Kildare Rebellion of 1534–5 against King Henry, Reynolds was dispatched as envoy to Rome to seek support from the Pope. In May 1535 he secured a papal promise to excommunicate King Henry of England. Reynolds died of an "incurable fever" and was buried in Archbasilica of St. John Lateran on 15 July 1535. The inscription on his grave slab in Rome gives accurate dates for his birth in Ireland, death in Rome, provides a family setting, and reveals the pope intended to consecrate him bishop. Reynolds was posthumously attainted of high treason in 1536.

His father was Maurus Mac Raghnaill, canon in the Church of Ardagh. Whether he had brothers or sisters is not recorded. His father or mother taught him Latin before enrolling him in school for children of nobility. By age fifteen he was a novice at the Augustinian Priory of Saint Mary in Mohill-Manachan, a monastery of the Canons regular of St. Augustine. The Canons Regular of Saint Augustine were one of several institutions born from an eleventh-century religious reform movement. The ecclesiastical branch of the Mac Raghnaill family had very strong associations with the Augustinian priory of Mohill, Co. Leitrim, from at least the fifteenth century. Nothing is known of his early life and ministries. Charles must have been highly regarded because sometime after completing his novitiate in Mohill, he was transferred, or moved, to the more important Diocese of Meath. In 1528 he was studying Canon law at the University of Oxford, a rare privilege for a native Irishman. Because the Mac
