Ælfwynn, wife of Æthelstan Half-King

Ælfwynn or Ælfwyn (died 8 July 983) was a member of a wealthy Anglo-Saxon family in Huntingdonshire who married Æthelstan Half-King, the powerful ealdorman of East Anglia, in about 932. She is chiefly known for having been foster-mother to the future King Edgar (ruled 959–975) following his mother's death in 944, when he was an infant.
