John Hastings, 3rd Earl of Pembroke (October 1372 – 30 December 1389) was the son of John Hastings, 2nd Earl of Pembroke and Anne Manny, 2nd Baroness Manny. He was also Baron Abergavenny.
He succeeded his father as an infant in 1375.
He married Elizabeth of Lancaster the daughter of John of Gaunt, in 1380, but the marriage was unconsummated (he was 8 and she 17 at the time of the marriage) and was annulled after she became pregnant by John Holland, whom she subsequently married.
He subsequently married Philippa Mortimer, daughter of Edmund Mortimer, 3rd Earl of March, but had no children, dying shortly afterwards in a jousting accident.
Death in a Joust
Richard II held his Christmas court at Woodstock Palace in 1389, and Pembroke took part in the Christmas sports, including jousting. While running a course against Sir John Des, he was struck in the groin by his opponent's lance and subsequently died of his injuries. Upon his death, the Earldom of Pembroke and the Barony of Manny became extinct, while the Barony of Hastings passed to a cousin.
He was described by the chronicler as being mourned by the common people as well as the nobility, by reason of his kind and generous nature.
