Cwenburh of Wimborne was an 8th-century Anglo-Saxon saint, a sister of King Ine of Wessex and of Saint Cuthburh. Her sister Cuthburh was married to King Aldfrith of Northumbria and then became the first abbess of Wimborne monastery. Very little information survives about Cwenburh. She is known primarily from a mention in a single annal of the Anglo-Saxon Chronicle: 718. In this year Ingild Ine's brother died, and their sisters were Cwenburh and Cuthburh. And Cuthburh raised the monastery at Wimborne; and she was given to Aldfrith, king of the Northumbrians; but they separated during his life.
