Werburh or Wærburh (also known as Werburgh and Werburga) (d. 3 February 699 at Trentham) is an English saint and the patron saint of Chester.
She was born at Stone (now in Staffordshire), and was the daughter of King Wulfhere of Mercia (himself the Christian son of the pagan King Penda of Mercia) and his wife St Ermenilda, herself daughter of the King of Kent. She was a nun for most of her life, and was tutored under her great aunt Etheldreda (or Audrey), the first Abbess of Ely and former queen of Northumbria.
Werburh was instrumental in convent reform across England. She eventually succeeded her mother Ermenilda, her grandmother Seaxburh, and great-aunt Etheldreda as fourth Abbess of Ely.
She was buried at Hanbury in Staffordshire and her remains were later transferred to Chester, of which church and monastery she became the great patroness (see Chester Cathedral). She is the last abbess whose name is recorded.
