Irene Doukaina or Ducaena (Greek: Εἰρήνη Δούκαινα, Eirēnē Doukaina; c. 1066 – 19 February 1138) was a Byzantine empress by marriage to the Byzantine emperor Alexios I Komnenos. She was the mother of Emperor John II Komnenos and the historian Anna Komnene. She was initially heavily overshadowed and humiliated in influence and power by her mother-in-law Anna Dalassene, but after her retirement and death, Irene was able to exert increasing influence over her husband Alexios I Komnenos, and became powerful towards the end of his reign. But even so, she could not arrange his successor according to her wishes, which favoured her daughter Anna Komnene over her son John II Komnenos.
