Sir James Keating, or Ketyng (died c. 1491) was an Irish cleric and statesman of the fifteenth century. He was Prior of the Irish house of the Knights Hospitallers at Kilmainham, and a member of the Privy Council of Ireland. Despite his political eminence and his clerical office, he was a man of ruthless character and violent temper, who once tried to murder a senior judge, and was later directly responsible for the death of his intended replacement as Prior. After a long and turbulent career, described by one historian as amounting to "thirty years of outrage, rapine and fraud", he was finally removed from the office of Prior in 1488 for his treason in supporting the Lambert Simnel Rebellion, and died in poverty a few years later.
