Seaxburh of Wessex

Seaxburh (; died ) was a queen of Wessex. She is also called Queen of the Gewisse, an early name for the tribe which ruled Wessex. She is said to have ruled Wessex for between one and two years after the death of her husband, Cenwalh, in 672. Her accession to the throne is documented in the Anglo-Saxon Chronicle for that year which states that "This year king Kenwalk died, and Sexburga his queen reigned one year after him". It was extremely rare for a woman to reign suo jure in Anglo-Saxon England, and she was the only woman to appear in a regnal list. Writing decades after Cenwalh's life, when Bede lists Cenwalh's accession, he mentions Seaxburh as the unnamed second wife whom the king married after he had cast away his first wife, who was the sister of the Mercian king Penda. It has been suggested that Bede deliberately omitted mention of Seaxburh because he viewed her marriage to Cenwalh, and therefore her right to the throne, as illegitimate.

Seaxburh was succeeded in about 674 by Æscwine, a descendant of Cenwalh's great-uncle Ceolwulf of Wessex.
