Quinidius was a 6th-century bishop and hermit who lived in Vaison-la-Romaine. Born into a noble Christian family, he initially pursued an ascetic life as a hermit near Toulon and Lérins Abbey. His reputation for piety eventually led him back to his birthplace, where he served as an archdeacon under Bishop Theodosius. Following his predecessor's death in 556, he ascended to the bishopric, where he became known for his dedication to the vulnerable and his participation in several important ecclesiastical councils.
