John Gordon PC (Ire) (23 November 1849– 26 September 1922) was an Irish lawyer and politician, who served as Attorney-General for Ireland and a Judge of the High Court.
He was educated at Queen's College Galway, a constituent college of the Queen's University of Ireland, where he held a senior scholarship in mathematics, graduating with a Bachelor of Arts degree in that subject (3rd class honours) in 1873, and Bachelor of Laws (LLB) in 1876.
On 1 October 1902, Gordon sent a letter to be read at the annual meeting of the Moray and Nairn Conservative Association.
In this letter, he cited growing tensions in Europe and abroad in order to call for increased unity within the United Kingdom, stating that "We shall need amid the gathering difficulties of the future a united national voice in support of our empire's interests in peace or in where when these are threatened by a world-wide rivalry"[1] In June 1915 when his party joined the Asquith coalition government, he was appointed Attorney-General for Ireland, an office he held until April 1916, when he was appointed a judge of the King's Bench division of the High Court of Justice in Ireland.
Maurice Healy, who vividly described many of the Irish judges of his youth in his memoir "The Old Munster Circuit" confessed that Gordon had made almost no impression on him, except that he refused to wear bright colours.
