Pega was an Anglo-Saxon anchoress who lived in the kingdom of Mercia during the late 7th and early 8th centuries. As the sister of Saint Guthlac and daughter of Penwalh, she belonged to a prominent Mercian noble family. She resided as a religious recluse near Peterborough, close to her brother's hermitage. Following Guthlac's death, she traveled to Rome, where she passed away in 719. She is recognized as a saint in the Catholic tradition and is commemorated on 8 January.
