Eadburh of Bicester (also Eadburth, or Edburg, death c. 650) [1] was an English nun, abbess, and saint from the 7th century.

She has been called a "bit of a mystery";[1] there have been several Saxon saints with the same name, so it is difficult to pinpoint which one was Eadburh.

It is most likely that Eadburh of Bicester was the daughter of King Penda of Mercia, who was pagan but had several children who were Christians.

[2] There are legends that claim that Edburgh and Edith found Osyth after she had drowned three days earlier and "witnessed her return to life".

[5] In 1182, her relics were moved to Bicester, when an Augustinian priory was founded by a group of Canons regular and dedicated to Saint Eadburgh and to the Virgin Mary.
