Opportuna of Montreuil

Opportuna of Montreuil (died 770) was a Frankish Benedictine nun and abbess. A Vita et miracula Sanctae Opportunae was written within a century of her death (c. 885–88) by Adalhelm (later rendered Adelin), bishop of Séez, who believed he owed his life and his see to Opportuna.
