John Keating, or Keatinge (c. 1630–1691) was an Irish judge of the late seventeenth century, who held office as Chief Justice of the Irish Common Pleas. He had an impressive reputation for integrity, impartiality and benevolence. Due to his loyalty to King James II of England, he was dismissed from his office as Chief Justice after the Revolution of 1688. Later, faced with the threat of impeachment, he committed suicide.
