Jonas (c. 760–843) was Bishop of Orléans and played a major political role during the reign of Emperor Louis the Pious.
Probably a cleric by the 780s, he served at the court of Louis the Pious, who ruled as King of Aquitaine during the reign of his father, Charlemagne.
He also wrote to refute some of the iconoclastic teachings of Claudius of Turin at the request of the emperor.
At the ecclesiastical council held in Paris in 825, Jonas presented the position of the Frankish clergy on Iconoclasm to Pope Eugenius II.
De Institutione regia, another mirror work, was written for Pippin of Aquitaine.
