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 succeeded his father as an infant in 1375, and also received lands from the death of William de Cantilupe the same year.
[1] 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.
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.
[4] Pembroke 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.
