Queen Wulfthryth of Wessex (fl. 868) was a queen consort of the kingdom of Wessex, the wife of King Æthelred. Her name is sometimes Latinized as Wulfrida or Wilfrida.
Little is known of Wulfthryth. She witnessed a charter of 868, in which she has the title of regina ("queen"). Which was exceptionally rare title for the King's consort in 9th-century England. The charter appears in the Codex Wintoniensis, but Wulfthryth is otherwise unrecorded in primary sources. Stephanie Hollis notes that 868 was the year of Alfred's marriage to a Mercian and that "Wulfthryth's name looks Mercian".
Wulfthryth is considered to be the likely mother of Æthelhelm (c. 865 – c. 890) and of Æthelwold (died 902), the leader of Æthelwold's Revolt.
