Philippa of Antioch (1148 – 1178) was Lady of Toron by her marriage to Humphrey II of Toron and a mistress of Andronikos I Komnenos.
Philippa was the younger daughter of Constance, Princess of Antioch and her first husband Raymond of Poitiers.[1] Philippa's siblings were Bohemond III of Antioch and Maria of Antioch, who married Manuel I Komnenos. In 1149, her father died in the Battle of Inab,[2] and her mother remarried in 1153 to Raynald of Châtillon.[1] From this marriage at least one daughter was born, Agnes who married Bela III of Hungary.[3]
Philippa encountered Andronikos I Komnenos at the court of the Principality of Antioch. Captivated by him, she was seduced and was his mistress from 1166–1167.[4]
After she was abandoned by Andronikos, Philippa married Humphrey II of Toron.[5] She and Humphrey however, had no children. Philippa died in 1178 around aged thirty. She was buried at the church of St. Mary in the Valley of Josaphat.[6]
