George Jeffreys, 1st Baron Jeffreys, PC (15 May 1645 – 18 April 1689), also known as "the Hanging Judge", was a Welsh judge. He became notable during the reign of King James II, rising to the position of Lord Chancellor (and serving as Lord High Steward in certain instances). His conduct as a judge was to enforce royal policy, resulting in an historical reputation for severity and bias.
