Ealhswith or Ealswitha (died 5 December 902) was the wife of King Alfred the Great. Her father was a Mercian nobleman, Æthelred Mucel, Ealdorman of the Gaini, which is thought to be an old Mercian tribal group. Her mother was Eadburh, a member of the Mercian royal family. Ealhswith is commemorated as a saint in the Christian East and the West on 20 July.
