Thecla of Kitzingen was an 8th-century Anglo-Saxon Benedictine nun, missionary, and abbess. Born in southern Britain, she was a relative of Saint Lioba and both women were educated at Wimborne Abbey. She became a key figure in the missionary efforts of Saint Boniface, traveling to Germany to assist in establishing and reforming monasteries. Throughout her religious career, she served in leadership roles, eventually supervising the abbey at Kitzingen following the death of its first abbess.
