Æthelwine of Lindsey was a Catholic bishop who served as the second leader of the diocese of Lindsey around 680. Very few historical details regarding his personal life are available, though he is mentioned in the writings of the historian Bede. He belonged to a notable English noble family, which included an abbot named Aldwin and an abbess named Æthelhild. His historical presence is primarily noted through these familial connections and his ecclesiastical role during the late seventh century.
