Caesaria of Arles was a 6th-century Gallo-Roman nun and abbess who lived in southern France. Born in Chalon-sur-Saône, she received her religious training at the foundation of John Cassian in Marseilles. She served as the first leader of the Saint-Jean convent, an institution established by her brother, Caesarius of Arles. Her leadership and holy lifestyle were noted by contemporary writers, including Venantius Fortunatus and Gregory of Tours, who praised her devotion.
