Wulfthryth, also known as Wilfrida (died c. 1000), was the second known consort of Edgar, King of England, in the early 960s. Historians disagree whether she was his wife or mistress. In 964, Edgar married Ælfthryth, and then or earlier Wulfthryth returned to Wilton Abbey, where she had been educated. She was accompanied by her daughter Edith, who was widely revered in the eleventh century as a saint. Wulfthryth remained there for the rest of her life as abbess and died on 21 September in an unknown year, around 1000. She was regarded as a saint at Wilton, but her cult did not spread more widely.
