Mildgyth was a 7th-century Anglo-Saxon abbess and the youngest daughter of King Merewalh of Mercia. As the youngest sibling of saints Mildburh and Mildrith, she is often symbolically associated with the theological virtue of hope. Following the religious life as a Benedictine nun, she eventually served as an abbess within a Northumbrian convent. Although historical details regarding her life are sparse, she is recognized for her religious devotion during the early medieval period.
