Judge Holden is a purported historical person who partnered with John Joel Glanton as a professional scalp-hunter in Mexico and the American Southwest during the mid-19th century. To date, the only source for Holden's existence is Samuel Chamberlain's My Confession: Recollections of a Rogue, an autobiographical account of Chamberlain's life as a soldier during the Mexican–American War. Chamberlain described Holden as the most ruthless of the roving band of mercenaries led by Glanton, with whom Chamberlain had traveled briefly after the war: '[he] had a fleshy frame, [and] a dull tallow colored face destitute of hair and all expression;' 'a man of gigantic size'; 'by far the best educated man in northern Mexico'; 'in short another Admirable Crichton, and with all an arrant coward'.

Samuel Emery Chamberlain was an American soldier, painter, and author who traveled throughout the American Southwest and Mexico during the mid-19th century.
