Maria Komnene (Greek: Μαρία Κομνηνή; 19 September 1085 – after 1136) was the second daughter of the Byzantine emperor Alexios I Komnenos.
Maria Komnene was born on Friday, 19 September 1085, as the second daughter and second child of the Byzantine emperor Alexios I Komnenos (r. 1081–1118) and Empress Irene Doukaina.
[9] Maria and Nikephoros had a number of children, but only two sons, Alexios Komnenos and Andronikos, are known by name, having held senior positions later in the century.
[13][12] The date of Maria's death is unknown, except that it occurred after 1136, when the deceased members of the imperial family were listed in the typikon of the Pantokrator Monastery.
[14] In her Alexiad, her older sister Anna Komnene speaks with great affection and praise for her virtue, especially for her actions during their father's final days.
