John Scott, 1st Earl of Clonmell PC (Ire) KC SL, known as The Lord Earlsfort between 1784 and 1789 and as The Viscount Clonmell between 1789 and 1793, was an Irish barrister and judge. Sometimes known as "Copperfaced Jack", he was Lord Chief Justice of the King's Bench for Ireland from 1784 to 1798.

The Court of King's Bench was one of the senior courts of common law in Ireland. It was a mirror of the Court of King's Bench in England. The Lord Chief Justice was the most senior judge in the court, and the second most senior Irish judge under English rule and later when Ireland became part of the United Kingdom. Additionally, for a brief period between 1922 and 1924, the Lord Chief Justice of Ireland was the most senior judge in the Irish Free State.
