John II of Luxembourg, Count of Ligny (1392–5 January 1441, Guise) was a French nobleman and soldier, a younger son of John of Luxembourg, Lord of Beauvoir and Marguerite of Enghien. His older brother Pierre received his mother's fiefs, including the County of Brienne, while John received Beauvoir. He took the side of the English during the Hundred Years' War, and carried out a number of chevauchées on behalf of the Regent Bedford. In 1425, he seized the seigneurie of Guise, which he had disputed with René of Anjou. At his death, he left Ligny and Guise to his nephew Louis.
