Frithugyth (floruit 737) was the wife of King Æthelheard of Wessex (died 740).
[1] Like her predecessor as Queen of Wessex, Æthelburg, wife of Ine of Wessex, Frithugyth is recorded in surviving charters, not merely witnessing her husband's donations of land to the church, but also making donations in her own right.
The principal donation attributed to Frithugyth is a sizable estate at Taunton, given to Winchester Cathedral in 737.
This was expanded by later Kings of Wessex and England, including Æthelwulf, Æthelstan, and Eadred, who refer to Frithugyth's earlier donation.
Frithugyth is reported by the Anglo-Saxon Chronicle to have made a pilgrimage to Rome in 737 along with Forthhere, Bishop of Sherborne.
