John Doukas, Latinized as Ducas, (Greek: Ἰωάννης Δούκας, Iōannēs Doukas; c. 1125/1127 – c. 1200) was the eldest son of Constantine Angelos by Theodora Komnene, the seventh child of the Byzantine Emperor Alexios I Komnenos and Irene Doukaina, from whose family name John Doukas took his own. He served as a military commander under Manuel I Komnenos and his nephew Isaac II Angelos, who raised him to the high rank of sebastokrator. Despite his advanced age, he continued to be an active general in the 1180s and 1190s, and until shortly before his death aspired to the imperial throne. He was the progenitor of the Komnenos Doukas line, which founded the Despotate of Epirus after the Fourth Crusade.
John was eldest son of the founder of the Angelos line, Constantine Angelos from Philadelphia, by Theodora Komnene, the seventh child of the Byzantine Emperor Alexios I Komnenos (ruled 1081–1118) and Empress Irene Doukaina. The couple, who married in 1110/15, had four sons and three daughters, of whom two, John and Andronikos (the father of the future emperors Isaac II Angelos and Alexios III Angelos), preferred to use their grandmother's far more prestigious surname of Doukas to their father's surname. The date of John's birth is unknown, and the only reference to his age is that in 1185 he was already an old man. The genealogist of the Komnenian family, Konstantinos Varzos, put his birth date approximately in 1125/27.
